Build it
What do you want thanks.io and Anthropic to do together?
Describe it and your agent reads both APIs, builds the automation, tests every branch and ships it. The list below is what exists today, not the limit.
Ask the assistant
You'll sign in before anything runs. What you typed comes with you.
Or work from Claude Code
Install the APIANT plugin for Claude Code and build, edit, test and read run history from your terminal. Every plan gets this, including free, and it spends no assistant credits.

Triggers and actions 3 triggers · 12 actions
Trigger
Item DeliveredTriggers when a postcard, letter, notecard, or giftcard is delivered to a recipient.
- New Order
Fires once for each new order placed in your thanks.io account.
- QR Code Scan
Triggers when a QR Code on a postcard, letter, or notecard is scanned. This will also trigger when a giftcard is redeemed.
- Add Recipient
Adds a recipient to your account and to an optional list. Only US or Canadian addresses are accepted. If no/invalid address is specified and a valid email address is, we'll attempt to look up a valid street address using the email address for a fee.
- Delete Recipient
Deletes a Recipient from Mailing List.
- Lookup Address by Email
Returns the mailing address on file for a recipient in a thanks.io mailing list, looked up by their email address. Returns an empty list of matches when no recipient in that list has the email.
Action
Anthropic agent messageRuns one AI agent turn on Anthropic and returns the model's reply. The turn is billed to the Anthropic account connected on this step, and the agent can call the account's AI tool automations.
- Cancel message batch
Cancel a Message Batch that is still processing.
- Count tokens in a message
Count the number of input tokens a Messages API request would use, without creating the message.
- Create message batch
Submit a batch of Messages API requests for asynchronous processing.
- Get message batch
Retrieve the status and request counts of a Message Batch by id.
- Get model
Retrieve details for a specific Claude model by id.
- List message batches
List Message Batches in the workspace, most recently created first.
- List models
List the available Claude models, most recently released first.
- Send model a message
Send a message to a Claude model and return its response. Supports the full Messages API: model, system prompt, multi-turn messages, max_tokens, tools, and adaptive thinking.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.
