Integration
Connect Adyen and Watermelon
When New payment authorisation fires in Adyen, your agent runs Add Contact in Watermelon, or New Contact in Watermelon to Add payment in Adyen. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Everything your agent can do with Adyen and Watermelon
Triggers and actions 8 triggers · 18 actions
- New payment authorisation
Webhook AUTHORISATION: result of authorisation request.
- New refund
Webhook REFUND: result of refund request.
- Add payment
Starts a payment (authorisation) in Adyen Checkout for the given amount, payment method and merchant account, and returns the payment's PSP reference and result code.
- Add payment link
Creates an Adyen Pay by Link payment link that a shopper can open to pay the given amount.
- Cancel payment
Cancels an authorised payment that has not been captured yet, releasing the funds back to the shopper. The final outcome arrives later in Adyen's CANCELLATION webhook.
- Capture payment
Captures an authorised payment (full or partial amount). Adyen processes the capture asynchronously: the response always has status "received" and the final outcome arrives later in a CAPTURE webhook.
- Delete stored payment method
Deletes (disables) a shopper's stored payment details token in Adyen.
- Get payment link
Retrieves the details of a payment link, including its amount, status (active, completed, expired or paymentPending), url and expiry.
- List payment methods
Retrieves the payment methods available for a transaction, based on details such as amount, country and currency, plus the shopper's stored payment methods when a shopper reference is given.
- List stored payment methods
Lists the tokens for payment details stored for a shopper, with a summary of each stored card or account.
- Refund payment
Refunds a captured Adyen payment, fully or partially. Adyen acknowledges the request immediately; the final outcome arrives later in a REFUND notification.
- Update payment link
Updates the status of an Adyen payment link. Adyen only allows setting the status to expired, which forces the link to expire so shoppers can no longer pay with it.

Triggers when a Watermelon conversation is archived.
- Handover Conversation Agent
Triggers when a Watermelon conversation is handed over to a human agent (its assigned agent changes).

No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.

What can your agent do in Watermelon when something happens in Adyen?
Any of Watermelon's 8 actions, including Add Contact, Find Contact, Find Conversation and Get conversation. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Watermelon to Adyen?
Yes. When something happens in Watermelon, your agent can act in Adyen too. This page covers both directions: Watermelon's triggers and Adyen's actions are listed here as well.
Do I have to build a connector for Adyen or Watermelon?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Adyen and Watermelon without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
