CONNECTING KARTRA WITH THE WORLD

Kartra API and IPN Replaces...

Native integrations are plug-and-play. Nothing to code, and no API to connect. We have done all the heavy lifting for you!

Native Integrations

Kartra integrates seamlessly with some of the biggest names in the industry, and we keep on building our connection network as we grow.

Mass email SMTPs to deliver your mailing campaigns to your users. We integrate with SendGrid, MailGun, Elastic Mail and Postmark.

On top of that, every Kartra account is provisioned with Kartra Mail, our own SMTP gateway in case you don't want to plug in your own.

Kartra Calendars syncs with Google Calendars and has easy integrations with Google Meet and Zoom to simplify your busy and ever-changing schedule.

Custom integrations

If you or your development team want to code your own custom integration with Kartra, our API, IPN and Custom App system will give you all the tools you need.

Make sure to read Kartra's technical documentation.

API

We offer both outbound and inbound API functionalities, so you can bridge your Kartra account with your own custom back-end code.
IPN

Kartra can send a notification to your application immediately as your customer places an order through Kartra Checkouts. The IPN will provide all relevant information of both the customer and the transaction.
Custom Apps

Are you perhaps coding your own App, software or SAAS? Do you want to connect it with Kartra so other people can benefit from the integration? Great! Our Custom App Program is ready to welcome you, and your creation, onboard!
