Attachment Upload API Reference
CAUTION: Attachment IDs expire after 90 days. After an attachment ID expires, you'll need to reupload your media to get a new attachment ID.
While reusable attachments will expire after 90 days and cannot be resent, attachments in message threads will never expire and are visible until a user deletes the message from the thread. If your use case allows, you can combine the upload and send steps as mentioned below to avoid this TTL issue.
The Attachment Upload API allows you to upload assets that can be sent in messages at a later time. This allows you to avoid the need to upload commonly used files multiple times. The API supports saving assets from a URL and from your local file system.
You may also use the Send API to simultaneously send a message with an attachment and save the attachment for later use. For more information, see the Upload and send section below.
Upload an attachment
To upload an attachment send a POST request to the /Your-page-id/message_attachments endpoint with message.attachment with type and payload. To be able to use the asset in multiple messages, set payload.is_reusable to true.
Example request for an upload from a URL
Formatted for readability. Replace bold, italics values, such as page_access_token, with your values.
curl -X POST "https://graph.facebook.com/v21.0/Your-page-id/message_attachments" \
-H "Content-Type: application/json" \
-d '{
"access_token":"Your_page_access_token",
"message":{
"attachment":{
"type":"image",
"payload":{
"url":"https://your-url.com/image.jpg",
"is_reusable": true
}
}
}
}'
Example request for an upload from a file
Formatted for readability. Replace bold, italics values, such as page_access_token, with your values.
curl -X POST -H "Content-Type: application/json" -d '{
"message": {
"attachment": {
"type": "image"
}
},
"filedata": "@/path-to-your-file/image.jpg",
"type": "image/png"
}' "https://graph.facebook.com/v21.0/{PAGE_ID}/message_attachments?access_token={PAGE_ACCESS_TOKEN}"
On success your app will receive a JSON object with attachment_id set to the ID of your attachment to be used in your messages.
{"attachment_id": "Your-attachment-ID"}
Send a message with an uploaded asset
To send a message with an asset that you have previously uploaded, uploaded with message.attachment.payload.is_reusable set to true, send a POST request to the /Your-page-id/messages endpoint with recipient.id, and the message.attachment object with type and payload.attachment_id.
Example request for an upload from a file
Formatted for readability. Replace bold, italics values, such as page_access_token, with your values.
curl -X POST -H "Content-Type: application/json" -d '{
"recipient": {
"id": "{PSID}"
},
"message": {
"attachment": {
"type": "image",
"payload": {
"attachment_id": "Your-attachment-ID"
}
}
}
}' "https://graph.facebook.com/v21.0/{PAGE_ID}/messages?access_token={PAGE_ACCESS_TOKEN}"
On success your app will receive a JSON object with success set to set to true.
{"success": "true"}Upload and send
You can also upload media and send it in a single API request.
CAUTION: Do not set is_public=true in the payload for this case. Attachments in the user's message thread are always private.
Example request for an upload from a URL
Formatted for readability. Replace bold, italics values, such as page_access_token, with your values.
curl -X POST -H "Content-Type: application/json" -d '{
"recipient": {
"id": "{PSID}"
},
"message": {
"attachment": {
"type": "image",
"payload": {
"url": "https://your-url.com/image.jpg"
}
}
}
}' "https://graph.facebook.com/v21.0/{PAGE_ID}/messages?access_token={PAGE_ACCESS_TOKEN}"
On success your app will receive a JSON object with success set to set to true.
{"success": "true"}
