I’ve encountered an issue when making calls to the blocks/create endpoint in the REST API (https://api.twitter.com/1.1/blocks/create.json). When using the chirpy python library, with some accounts (but not all, seemingly), calls to it are returning a 200 status code, indicating that the block was created, but then logging into Twitter as that user shows it wasn’t. Identical calls to the endpoint made via Apigee succeed, so this may be in some way specific to chirpy, but that still doesn’t explain why it’s returning a status code indicating success.
This has been resolved, and is confirmed to not be an issue with Twitter. Moderators/admins, feel free to delete this topic (since it seems I can’t).
Thanks for letting us know - glad you got it worked out.
