Describe the flow you need, at any depth, and your agent builds it and tests every scenario before it ships. Everything your agent can do with Adyen and Lettermint ## Triggers and actions 2 triggers · 18 actions - Trigger **New payment authorisation** Webhook AUTHORISATION: result of authorisation request. - Trigger **New refund** Webhook REFUND: result of refund request. - Action **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. - Action **Add payment link** Creates an Adyen Pay by Link payment link that a shopper can open to pay the given amount. - Action **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. - Action **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. - Action **Delete stored payment method** Deletes (disables) a shopper's stored payment details token in Adyen. - Action **Get payment link** Retrieves the details of a payment link, including its amount, status (active, completed, expired or paymentPending), url and expiry. - Action **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. - Action **List stored payment methods** Lists the tokens for payment details stored for a shopper, with a summary of each stored card or account. - Action **Refund payment** Refunds a captured Adyen payment, fully or partially. Adyen acknowledges the request immediately; the final outcome arrives later in a REFUND notification. - Action **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. - Action **Add domain** Adds a new sending domain to your Lettermint team and returns the DNS records needed to verify it. - Action **Add suppression** Adds one email address, or up to 1,000 addresses, to the team, project or route suppression list so Lettermint stops sending to them. - Action **Delete domain** Deletes a sending domain from your Lettermint team. - Action **Delete suppression** Removes an email address from the team's suppression list so it can be mailed again. Spam complaint suppressions stay active while Lettermint reviews the removal. - Action **Get domain** Returns the details of a Lettermint sending domain, optionally including its DNS records and associated projects. - Action **List domains** Returns the sending domains on your Lettermint team, optionally filtered by project, status or name. - Action **List projects** Returns the projects in your Lettermint team, optionally filtered by a search term and sorted. - Action **List suppressions** Returns the suppressed email addresses and domains on your team, with their reason, scope and dates. ## Each app on its own - [ **Adyen** Payment infrastructure platform enabling enterprises to accept, settle, and move funds globally with...](https://apiant.ai/connections/adyen) - [ **Lettermint** Lettermint is an EU-based transactional email delivery service.](https://apiant.ai/connections/lettermint) Reviews ## What our customers say ## More from Adyen - [ **Adyen to Gravity Forms** Gravity Forms is a premier WordPress plugin that makes it easy to create powerful forms on the fly.](https://apiant.ai/connect/adyen-to-gravity-forms) - [ **Adyen to BigML** BigML is a machine learning platform for building, evaluating, and running predictive models.](https://apiant.ai/connect/adyen-to-bigml) - [ **Adyen to Erpnext** Open-source ERP system for accounting, inventory, manufacturing, sales, projects, and CRM.](https://apiant.ai/connect/adyen-to-erpnext) - [ **Adyen to Gift Up!** Gift Up! is a digital gift card system for your website or Facebook page.](https://apiant.ai/connect/adyen-to-gift-up) - [ **Adyen to Google Slides** Google Slides is a cloud-based presentation editor with real-time collaboration, template gallery, and...](https://apiant.ai/connect/adyen-to-google-slides) - [ **Adyen to The Muse** Job board and company profiles](https://apiant.ai/connect/adyen-to-the-muse) ## More into Lettermint - [ **HubSpot to Lettermint** HubSpot is your all-in-one stop for all of your marketing software needs.](https://apiant.ai/connect/hubspot-to-lettermint) - [ **Salesforce to Lettermint** Salesforce is a leading enterprise customer relationship management (CRM) platform.](https://apiant.ai/connect/salesforce-to-lettermint) - [ **Slack to Lettermint** Slack is a messaging platform for teams.

Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Lettermint when something happens in Adyen? Any of Lettermint's 8 actions, including Add domain, Add suppression, Get domain and List domains. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Lettermint to Adyen? Lettermint has no triggers in the catalog today, so automations start in Adyen. If you need the other direction, ask: your agent reads Lettermint's API documentation and adds it. ### ### Do I have to build a connector for Adyen or Lettermint? 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 Lettermint 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.
