FAQPage Schema

How do I send a file to a Feishu chat using the REST API?▼

To send a file to Feishu chats via the REST API, upload the binary to the Feishu files endpoint to get a file_key, then post a msg_type file payload to the messages endpoint with the target chat_id.

What's the best way to forward generated documents to Feishu groups?▼

Forwarding documents to Feishu groups is done by uploading the attachment to the files endpoint to obtain a file_key, then sending a file message to the specific chat_id using the bot's tenant_access_token.

Do I need a tenant_access_token to upload attachments for Feishu bot delivery?▼

Yes, obtaining a tenant_access_token is required to authenticate the bot, upload binary attachments via the files endpoint, and deliver the file message to the designated Feishu chat or user.

Can I use text-only messaging flows to share files in Feishu?▼

No, sharing files in Feishu requires using a file messaging flow where the attachment is uploaded first to get a file_key, rather than relying on text-only messaging payloads.

Why does my Feishu file message fail to deliver to the target chat?▼

Feishu file message delivery fails when the bot lacks appropriate scopes, the tenant_access_token is missing, or the receive_id_type is not set correctly to match the target chat_id in the messages endpoint payload.

Does sending a file message in Feishu require a specific receive_id_type?▼

Yes, sending a file message in Feishu requires setting receive_id_type to chat_id in the messages endpoint payload to ensure the file is delivered to the correct group or direct chat.
