Introduction
Authentication
Authenticate your requests using access token available in Amio settings. Your access token carry many privileges, so keep it secret! You can authenticate your requests using Authorization HTTP header or by sending access token in query parameters.
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer {{OAUTH_TOKEN}}" https://api.amio.io/v1/messagescurl -X POST -H "Content-Type: application/json" https://amio.io/api/v1/messages?access_token={{OAUTH_TOKEN}}Get Access Token
- Login to app.amio.io.
- Navigate to API settings.
- Copy the access token.
Requests
All API requests must be made over HTTPS with base URL https://api.amio.io/v1/. Data is sent and received in JSON format. Where possible, Amio API leverages appropriate HTTP verbs for requests.
GET
Used for resource retrieval.
POST
Resource creation or any other non-idempotent operation.
PUT
Used for idempotent operation as collection replacement etc.
PATCH
Update resource. Use {"key": "value"} for property update or create and {"key": null} for delete.
DELETE
Deletes a resource.
Responses
HTTP status codes are used to communicate result of your request.
200 OK
The request was successful.
201 Created
The request was successful and resource was created.
204 No Content
The request was successful and resource was deleted.
400 Bad Request
When the request could not be understood.
401 Unauthorized
Unauthorized request, i.e. missing access token.
403 Forbidden
The request is forbidden due to security reasons.
404 Not Found
Requested resource cannot be found.
405 Method Not Allowed
Requested method was not allowed, some other HTTP method is required.
422 Unprocessable Entity
The request was understood but cannot be processed as some validation error might occur. This might also represent an invalid state of the application or other similar problems.
429 Too Many Requests
In case you exceed maximum number of requests within given period, you receive this error response for any consequent requests. See Rate Limiting for more details.
502 Bad Gateway
In case an underlying API responds with an error. For example this might occur when message is being send to Facebook Messenger and Facebook page is disconnected from Amio.
All responses with status code 201 Created contain Location header with actual location of newly created resource, i.e. Location: https://api.amio.io/v1/channels/{channel_id}.
Errors
As the HTTP status code returns a basic information about an error, we provide additional data in response body for further error indication. All errors have following format:
{
"timestamp": "{{iso_8601_timestamp}}",
"status": {
"code": "{{HTTP_STATUS_CODE}}",
"message": "{{HTTP_STATUS_MESSAGE}}"
},
"errors": ["{{LIST_OF_DETAIL_ERRORS}}"]
}{
"timestamp": "2016-12-21T11:17:56.397Z",
"status": {
"code": "405",
"message": "Method Not Allowed"
},
"errors": [
{
"message": "Method POST is not allowed for resource /users."
}
]
}{
"timestamp": "2016-12-21T11:17:56.397Z",
"status": {
"code": "422",
"message": "Unprocessable Entity"
},
"errors": [
{
"field": "recipient",
"rejected_value": null,
"message": "Property 'recipient' cannot be null."
}
]
}Pagination
A resource which returns a list doesn't return all results at once. Instead, the number of results is constrained and you can traverse the results. For that purpose, the list requests accept the parameters max and offset.
max
10
Maximal number of returned resources. Maximal allowed value is 100.
offset
0
The offset from the first result to list from.
All list responses return a number of total results in HTTP response header.
x-total-count
Number of total results.
An example which returns the 21st to 30th resource:
curl-H "Content-Type: application/json" -H "Authorization: Bearer {{OAUTH_TOKEN}}" https://api.amio.io/v1/channels?max=10&offset=20Rate Limiting
Amio API has different rate limits for each pricing plan. We limit number of requests you can do within a hour. And number of simultaneous connections you can have opened to Amio servers.

You can check the returned HTTP headers of any API request to see your current rate limit status for maximum number of requests:
curl -i https://api.amio.io/v1/channels/{{channel_id}}
HTTP/1.1 200 OK
Date: Mon, 01 Jul 2013 17:27:06 GMT
Status: 200 OK
X-RateLimit-Limit: 1000
X-RateLimit-Remaining: 999
X-RateLimit-Reset: 1491820066X-RateLimit-Limit
The maximum number of requests that you are permitted to make per hour.
X-RateLimit-Remaining
Remaining number of requests.
X-RateLimit-Reset
Remaining time before the rate limit resets, in UTC epoch seconds.
Once you go over the rate limit you will receive an error response:
{
"timestamp": "2016-12-21T11:17:56.397Z",
"status": {
"code": "429",
"message": "Too Many Requests"
},
"errors": [
{
"message": "You have exceeded maximum number of requests and have been temporarily blocked. See documentation for more details: https://docs.amio.io/reference#rate-limiting"
}
]
}Messages
Messages resource is the main entry point for sending messages. You have to specify a channel and contact to deliver the message.

Contacts
Contact represents the end user on given channel. Contact is automatically created whenever you receive a message from the user for the first time. However, there are also different ways how you can create the contact (i.e. for Mobile platform the user is created when you send a message to the given phone number).
Contact Merging
Amio doesn't implement any type of contact merging for one user on different platforms.
See channel specific requests to see differences between contacts on each channel:
List Contacts
Get Contact
Delete Contact
Deleting a contact will also delete its conversation, messages and linked files.
Settings
Settings resource is used for setting up certain properties of a channel like get started button, menu, etc.
Settings are available only on some channels:
Webhooks
Webhooks allow you to receive real-time updates when a specific event occurs, i.e. message is received from a contact. These events are HTTP POST requests being sent to an endpoint of your server. Similarly to Amio Messaging API, body of such request is in JSON format. All events which happen in a specific channel are delivered to a single webhook url (i.e. https://your-server.com/webhook) which you can set in administration.
When you receive a webhook event, you should always return HTTP response in 2xx class, i.e. 200 OK in shortest time possible (we close the connections which takes longer then 60 seconds). If the webhook request fails or exceeds the maximum time, Amio will try to re-deliver the webhook again later (see Webhook Re-Delivery).
All webhooks have following body structure:
{
"event": "{{EVENT_NAME}}",
"timestamp" : "{{ISO_8601_TIMESTAMP}}",
"data" : {
"{{event type specific data}}"
}
}data
object
Event type specific data object.
If your webhook fails with response code 4xx or 5xx, Amio will try to re-deliver the webhook again. There are several re-delivery events after 1, 5, 20, 60, 180 and 480 minutes. If all retries fail, the webhook call is discarded.
Set Webhook URL
- Login to app.amio.io.
- Pick a channel from channels.
- Select tab Webhook and set Webhook Url.
Events
Different events are fired by Amio. There are common events to all channel types, however, there are also events specific to each channel, see Channel Events chapter for a complete list of channel-specific events.
Message Received
This event is fired when a contact sends a message to your channel. Request body contains channel type on which the event was handled as well as id of the contact. Different type of messages can be received based on channel.type.
{
"event": "message_received",
"timestamp": "2016-10-06T13:42:48Z",
"data": {
"id": "{{MESSAGE_ID}}",

"native_data": {}
},
}
}data
object
Object representing message received. Different type of messages can be received (text, image, etc.). The structure matches Send Message response body except for the nlp key (see below). This key will be present only for received text messages on channels with NLP integration connected.
If there's an NLP integration connected to your channel, then your Message Received webhook will contain an nlp key with the result provided by the NLP service. Since different NLP services provide different extra capabilities and parameters beyond simple intent/entity extraction, we also include full JSON response from the service.
nlp.intents
array of objects
List of intents ordered by confidence score.
nlp.intents[].id
string
Name (or other unique identifier) of the intent.
nlp.intents[].confidence

Message Failed
This event occurs only for some platforms and notifies you about a message that could not be. This may happen when given phone number is wrong or message expires, etc.
{
"event": "message_failed",
"timestamp" : "2017-12-29T17:26:17.331Z",

}
}data.channel
object
Channel where the data.contact resides in.
data.contact

Message Echo
Message echo event is invoked whenever a message is sent to a contact. This callback allows you to track all messages being sent no matter if they're sent by your channel or by someone else. For example, messages sent to Facebook users directly from Facebook Page administration or messages sent by some other Amio channel can be easily recorded.
{
"event": "message_echo",
"timestamp": "2016-10-06T13:42:48Z",

"payload": "We know, we try really hard to bring always something more to our beloved customers!"
},
"metadata": {
"any": "arbitrary data"
}
}
}data
object
Object representing message which is echoed. Different type of messages can be received (text, image, etc.). The structure matches Send Message response body.
Security
Once your server is configured to receive webhook events, it'll listen for any payload sent to the endpoint you configured. For security reasons, you probably want to limit requests to those coming from Amio. There are few ways to go about this, for example, you could opt to whitelist requests from Amio's IP address but a far easier method is to set up a secret token and validate the information using secret token.
You can find your secret token in Amio settings.
Amio uses this secret token to create a hash signature with each payload. The HTTP request will contain an X-Hub-Signature header which contains the SHA1 signature of the request payload, using the secret token as the key and prefixed with sha1= string. Your callback endpoint can verify this signature to validate the integrity and origin of the payload.
Here is the code how to calculate X-Hub-Signature:
const crypto = require('crypto')
function calculateXHubSignature(secret, body /* as string */) {
const hmac = crypto.createHmac('sha1', secret)
hmac.update(body)
return `sha1=${hmac.digest('hex')}`
}import org.apache.commons.codec.binary.Hex
import javax.crypto.Mac
import javax.crypto.spec.SecretKeySpec
import java.nio.charset.Charset
class WebhookSecurityService {
public static String calculateXHubSignature(String secret, String body) {
Mac hmac = Mac.getInstance("HmacSHA1");
hmac.init(new SecretKeySpec(secret.getBytes(Charset.forName("UTF-8")), "HmacSHA1"));
return "sha1=" + Hex.encodeHexString(hmac.doFinal(body.getBytes(Charset.forName("UTF-8"))));
}
}// credits goes to Michal Pustějovský <mpustejovsky@dpd.cz>
using System;
using System.Text;
using System.Security.Cryptography;
namespace Webhook
{
public class WebhookSecurityService
{
public string WebhookSecurity(string secret, string body)
{
var hmac = new HMACSHA1(Encoding.UTF8.GetBytes(secret));
var byteHash = hmac.ComputeHash(Encoding.UTF8.GetBytes(body));
return "sha1=" + BitConverter.ToString(byteHash).Replace("-", "").ToLower();
}
}
}Verify your algorithm with following values:
secret = 'WebhookSecret'
body = '{"event":"messages_delivered","timestamp":"2018-03-01T11:54:14.886Z","data":{"channel":{"id":"viber_service_messages_test","type":"viber"},"contact":{"phone_number":"+420606123456"},"messages":[{"id":"151990525359991"}]}}'
The calculated X-Hub-Signature should equal to sha1=cb041d03489e961730cb6c7a6d1edf58ae88ef13.
Facebook Messenger
See Amio Documentation for getting started manuals and complete description of Facebook Messenger platform.
Messages
Message resource is the main entry point for sending messages. To send a message, you have to specify a Facebook contact with one of the following attributes:
- Contact Id - contact id
- Phone Number
- User Ref - received from Opt-in Webhook
Contact Id
{
"contact": {
"id": "6456078781510718339"
},
"channel": {},
"content": {}
}You receive contact.id when the user starts a conversation with you, see Entry Points for more details.
Phone Number
You can send a message using a phone number you already have (see Phone Number Entry Point for more details). Attributes first_name and last_name are optional and just help to match the phone number with an existing Facebook User.
{
"contact": {
"phone_number": "+1 (555) 857-6309",
"first_name": "Anthony",
"last_name": "Hopkins"
},
"channel": {},
"content": {}
}{
"id": "...",
"contact": {
"id": "15234390803083474",
"phone_number": "15558576309"
},
"channel": {},
"content": {}
}Opt-in and Messages Delivered Webhooks
When you send a message using phone number, you can listen to Opt-in Webhook which is fired when the user confirms your request. You should however also listen to Messages Delivered Webhook which is fired for any further message sent after the user opts in.
Phone Number Format
Note that the phone number in response is in E.164 format. All responses and webhooks coming from Amio use this format.
Message Tags
Facebook requires you to comply with subscription messages policy when sending messages using phone number. This applies for all messages sent before the user opts in to receive messages from you.
Therefore, when you send messages before the opt-in, Amio automatically sets tag non_promotional_subscription (see tags) to your messages. You can set appropriate message tag which will be used after the user opts in (i.e. shipping_update).
User Ref
Opt-in Webhook delivers a user_ref attribute which can be used for sending the first message to the user.
List Messages
id
string
Id of the message.
direction

Facebook Messenger receipt.
Receipt detail is shown when user taps on the receipt.
Structure
Structure messages allows you to send well formatted message containing image, title, description, link and action buttons. This format is suitable when you'd like to send messages with visual content and possible call to action buttons, i.e. today's menu of your restaurant.
Different Structure Messages
Structure message can be composed from subset of attributes: title can be combined with one or more attributes (i.e. Title & Text, Title, Text & Image, etc.), text can be combined only with title or button (Title & Text and Text & Button).
Structure - Horizontal Scroll
It is also possible to send multiple structured messages. They are displayed as a horizontal scroll within the Facebook Messenger.
Buttons
Buttons can be used in Structure messages. They provide the user with ability to perform a predefined action, such as opening Messenger webview, send a postback message, share a content, and more.
- Url Button
- Postback Button
- Call Button
- Share Button (coming soon)
- Buy Button (coming soon)
- Log In Button (coming soon)
- Log Out Button (coming soon)
The Url Button opens an in-app Messenger webview (browser) with given address.
buttons: [

"title": "Freedom",
"payload": "https://en.wikipedia.org/wiki/Liberty"
}
]
type*
string
Must be set to url.
title*
string
Title of the button. Max size is 20 characters.
payload*
string
Url to be opened.
Requires Domain Whitelisting
Url passed to the webview with url button must be whitelisted (including subdomains). See domain whitelisting.
Postback Button
When the user taps on the postback button, it sends developer-defined payload back on Postback Received webhook. You can perform an action or reply back when this happens.
buttons: [
{
"type": "postback",
"title": "List Items",
"payload": "{{PASS_THROUGH_PARAM}}"
}
]
type*
string
Must be set to postback.
title*
string
Title of the button. Max size is 20 characters.
payload*

"title": "Call Us",
"payload": "+1 (555) 857-6309"
}
]
type*
string
Must be set to phone.
title*
string
Title of the button. Max size is 20 characters.
payload*
string
Phone number that will be dialed. Make sure the phone number is in international format.
Quick Replies
Quick Replies are buttons with a set of pre-defined short replies that appear above the user input, making the keyboard less important. When a button is tapped, the message is sent as a text and you'll receive it to your webhook. The buttons are dismissed as soon as user taps one or reply with own text.
Quick Replies can be attached to any Message type in the content.quick_replies attribute.
{
"channel": { },
"contact": { },
"content": {
"type": "...",
"payload": "...",
"quick_replies": [
{ "..." },
{ "..." },
{ "..." }
]
}
}quick_replies
array of objects
Holds a list of maximally 11 objects of Text Quick Reply, User Location Quick Reply, Email Quick Reply or Phone Number Quick Reply type.
Text Quick Replies show buttons with text and optionally a small image icon. Each button can also hold a developer-defined payload, which is invisible to the user but can be used for automated processing. When the user taps on the button, it fires Message Received webhook with text and developer payload if specified.
"quick_replies": [
{
"type": "text",
"title": "Pilsner Urquell",
"payload": "DEVELOPER_DEFINED_PAYLOAD",
"image_url": "http://www.logotypes101.com/logos/778/70D1EF7E13BFAC232F2D05DE2E5594E0/pubisc.png"

"image_url": "http://www.logotypes101.com/free_vector_logo_png/33082/85D3F063102F2476DC36D26D4D7A15C1/Heineken29"
}
]
type*
string
Must be set to text.
title*
string
Button title with limit of 20 character; longer text gets truncated.
payload*
string
Developer-defined payload with limit of 1000 character. This payload is delivered back together with title as a text message in Message Received webhook.
image_url
string
Image to be displayed on the button. It should have dimension of at least 24x24 px.
UX - `payload` might not be delivered
Be aware that the user might send the reply by typing it into user input. In this case you don't receive the payload metadata. However, you should handle this message same as the user taps on the quick reply button.
Users can be prompt for their location via quick replies. It shows a Send Location button. When the user taps on the button, it fires Message Received webhook with location coordinates.
"quick_replies": [
{
"type": "location"
}
]
type*

Types
Facebook Messenger types are used to explicitly specify the purpose of a message and ensure that given message complies with Facebook policies. Amio uses default message type so you don't have to care about setting this attribute. However, you can specify a message type for advanced scenarios.
To send a message type, you can use type reserved keyword in metadata attribute:
{
"channel": { },
"contact": { },
"content": { },
"metadata": {
"type": "response"
}
}type
string
Message type: response, update. Type can be set only if Tags are not used.response (default): Message is in response to a received message. This includes promotional and non-promotional messages sent inside the 24-hour standard messaging window or under the 24+1 policy. For example, use this tag to respond if a person asks for a reservation confirmation or an status update.update: Message is being sent proactively and is not in response to a received message. This includes promotional and non-promotional messages sent inside the the 24-hour standard messaging window or under the 24+1 policy.

Get Settings
user_input_enabled
boolean
Enables or disables the user from sending a text message to you, see User Input enabled.
domains_whitelist
array
Some Facebook Messenger features needs to have used domains whitelisted, see Domains Whitelist.
Get Started Button
Get Started Button is visible on the welcome screen when the user comes for the first time. If the user tapes the button, it will trigger Postback Received webhook and deliver the user's page-scoped id.
You can then present a personalised message to greet the user or provide a structured message with buttons to prompt him or her to take an action. The button is a good mean to increase conversions. Adding a "Get Started" button resolves the issue of users not knowing what to write to break the ice with your bot.
Get started button on conversation start.
Menu
Creating a menu in Facebook Messenger, you can highlight important actions or provide link to a webpage. Menu for Facebook Messenger is hierarchical and consists of different menu item types:
- Url
- Postback
- Nested Menu

- Facebook Messenger has a version 106 and above.
- The attached Facebook page must be published.
Nested menu items.

- Click Settings in your Facebook Page.
- Click Messenger Platform on the left menu.
- Edit domains in Whitelisted Domains sectionn.
