Question 1

How do I handle incoming messages with go-lark in a Gin app?

Accepted Answer

Use the larkgin middleware: set it up in your Gin router, then extract events from the context to process messages. Examples in the repository show how to handle URL challenges and message callbacks step-by-step.

Question 2

Does go-lark support interactive cards for Feishu bots?

Accepted Answer

Yes, it supports interactive cards via MsgBuffer with CardBuilder. You can build custom cards with buttons and handle actions using the provided middleware for callbacks.

Question 3

go-lark vs official Feishu SDK: which is better for Go?

Accepted Answer

go-lark is community-driven and offers a more idiomatic Go API with utilities like middleware and MsgBuffer, while the official SDK might have broader API coverage. For Go-focused projects, go-lark is often preferred due to its ease of use.

Question 4

How to debug a go-lark bot locally?

Accepted Answer

Use ngrok to expose your local server, then configure your bot's webhook to the ngrok URL. The SDK also provides PostEvent to simulate incoming events for testing without live traffic.

Question 5

Is go-lark compatible with Lark Suite endpoints or only Feishu?

Accepted Answer

It defaults to Feishu but can switch to Lark using SetDomain(lark.DomainLark). However, full compatibility isn't guaranteed as testing is primarily on Feishu, so you may encounter untested edge cases.

Question 6

Can I use go-lark to send file messages?

Accepted Answer

Yes, but files must be uploaded to the Lark server first. Use MsgBuffer with the File function after uploading, as detailed in the message buffer documentation.
