Message management

This page shows how to call Chat RESTful APIs to send different types of messages, upload and download files, and retrieve historical messages.

Before calling the following methods, make sure you understand the call frequency limit of the Chat RESTful APIs as described in Limitations.

Common parameters​

The following table lists common request and response parameters of the Chat RESTful APIs:

​

Parameter	Type	Description	Required
host	String	The domain name assigned by the Chat service to access RESTful APIs. For how to get the domain name, see Get the information of your project.	Yes
org_name	String	The unique identifier assigned to each company (organization) by the Chat service. For how to get the org name, see Get the information of the Chat project.	Yes
app_name	String	The unique identifier assigned to each app by the Chat service. For how to get the app name, see Get the information of the Chat project.	Yes
username	String	The unique login account of the user. The user ID must be 64 characters or less and cannot be empty. The following character sets are supported: 26 lowercase English letters (a-z) 26 uppercase English letters (A-Z) 10 numbers (0-9) "_", "-", "." The username is case insensitive, so Aa and aa are the same username. Ensure that each username under the same app is unique. Do not set this parameter as a UUID, email address, phone number, or other sensitive information.	Yes

​

Parameter	Type	Description
action	String	The request method.
organization	String	The unique identifier assigned to each company (organization) by the Chat service. This is the same as org_name.
application	String	A unique internal ID assigned to each app by the Chat service. You can safely ignore this parameter.
applicationName	String	The unique identifier assigned to each app by the Chat service . This is the same as app_name.
uri	String	The request URI.
path	String	The request path, which is part of the request URL. You can safely ignore this parameter.
entities	JSON	The response entity.
timestamp	Number	The Unix timestamp (ms) of the HTTP response.
duration	Number	The duration (ms) from when the HTTP request is sent to the time the response is received.

Chat RESTful APIs require Bearer HTTP authentication. Every time an HTTP request is sent, the following Authorization field must be filled in the request header:

_1

Authorization: Bearer ${YourAppToken}

In order to improve the security of the project, Agora uses a token (dynamic key) to authenticate users before they log in to the chat system. Chat RESTful APIs only support authenticating users using app tokens. For details, see Authentication using App Token.

This group of methods enable you to send and receive peer-to-peer and group messages. Message types include text, image, voice, video, command, extension, file, and custom messages.

For each App Key, the call frequency limit of this method is 100 per second.

Follow the instructions below to implement sending messages:

• For text, command, and custom messages: Call the send-message method, and pass in the message content in the request body.
• For image, voice, video, and file messages:
  1. Call the upload-file method to upload images, voice messages, videos, or other types of files, and get the file file_uuid from the response body.
  2. Call the send-message method, and pass the file_uuid in the request body.

• When calling the RESTful APIs to send a message, you can use the from field to specify the message sender.
• If the data length of the request body exceeds 5 KB, error code 413 will be returned. The maximum data length of the request body and extension fields is 3 KB.

This method sends a message to a peer user.

This RESTful API allows you to send a maximum of 100 messages to 10 chat rooms in total on each call. Assuming that you send two messages to 10 chat rooms, the server counts it as 20 messages.

You can set the priority of a certain message type or chat room member to high, normal, or low. In this case, when the server is overloaded, low-priority messages can be dropped to reserve resources for the high-priority ones. This ensures that high-priority messages are sent first.

Note that this feature can increase the delivery reliability of high-priority messages, but cannot guarantee the deliveries. Even high-priorities messages can be dropped when the server load goes too high.

POST https://{host}/{org_name}/{app_name}/messages/chatrooms

For the descriptions of the path parameter, see Common Parameters.

Parameter	Type	Description	Required
Content-Type	String	The content type. Set it to application/json.	Yes
Accept	String	The content type. Set it to application/json.	Yes
Authorization	String	The authentication token of the user or administrator, in the format of Bearer ${token}, where Bearer is a fixed character, followed by an English space, and then the obtained token value.	Yes

The request body is a JSON object, which contains the following parameters:

Parameter	Type	Description	Required
to	Array	An array of the chat room IDs that receives the message. Within one second, you can send messages to a maximum of 100 chat rooms, and for each request, you can send messages to a maximum of 10 chat rooms.	Yes
chatroom_msg_level	String	The chat room message priority: high (Default) normal low	No

The other parameters and descriptions are the same with those of Sending a one-to-one message method.

If the returned HTTP status code is 200, the request succeeds, and the response body contains the following parameters:

Parameter	Type	Description
data	JSON	The detailed content of the response. The value of this parameter includes a key-value pair where key represents the chat room ID that receives the message and value the message ID. For example, if the returned data is "185145305923585": "1029545553039460728", it means that a message with the ID of 1029545553039460728 is sent in chat room 185145305923585.

For the other parameters and descriptions, see Common parameters.

This method enables you to upload images, audios, videos, or other types of files. For images and videos that have thumbnails, note the following:

• Images: After uploading an image, the Agora server automatically generates the thumbnail of the image.
• Videos: The Agora server does not generate thumbnails for videos automatically. After uploading a video, you must recall this method to upload the thumbnail for the video yourself.

File size	Thumbnail size
≤10	The size of the thumbnail remains the same as that of the original file.
>10	A thumbnail is generated based on the specified thumbnail-height and thumbnail-width parameters.
	If you leave thumbnail-height and thumbnail-width empty, the height and width of the thumbnail is 170 × 170 pixels by default.

Take note of the following considerations before calling this method:

• You cannot upload a file larger than 10 MB.
• You can restrict access to the uploaded file by requiring users to provide an access key before they can download the file. The format of the key is {{url}}?share-secret={{secret}}.

For each App Key, the call frequency limit of this method is 100 per second.
