Question 1

How do I handle Lark webhooks in Go?

Accepted Answer

Use the SDK's event callback framework: initialize with encryption keys, register handlers like EventV2IMMessageReceiveV1, and expose an HTTP endpoint to listen. The README includes a full example for processing message events and replying.

Question 2

Lark Go SDK vs writing my own API client – which is better?

Accepted Answer

This SDK saves time with complete API coverage, generated code, and built-in auth, but if you only need a few endpoints or want total control over HTTP handling, a custom client might be simpler. The mock testing support here is a key advantage for reliability.

Question 3

Can I use this for Lark ISV apps in Go?

Accepted Answer

Yes, it supports ISV apps with tenant-specific clients and token management. The README shows how to create a client with ISV mode and a store for multi-tenant operations.

Question 4

How to test my Lark integration without hitting real APIs?

Accepted Answer

Leverage the SDK's mocking support: use generated mocks to simulate API responses in unit tests. This is highlighted in the features and helps avoid rate limits or side effects during development.

Question 5

Is there a way to manage user access tokens for OAuth2 in this SDK?

Accepted Answer

Yes, it includes user access token management for OAuth2 flows, handling token refresh and storage internally, as mentioned in the key features for user-level API calls.

Question 6

What if Lark's API changes – does this SDK update automatically?

Accepted Answer

No, updates require pulling new SDK versions since it uses code generation from Lark's specs. The maintainer must regenerate code, so you need to monitor releases for breaking changes.
