Test and troubleshoot

Install the corresponding plugin and configure its required accounts, channels and secrets. Test an API read before a write operation. An external-service error is not a reason to recreate the whole bot.

Save, validate and publish. Perform one real test and read the first relevant log error. [Testing](/docs/flow-testing) · [Variables](/docs/flow-variables) · [Permissions](/docs/flow-permissions).
