The OnePageCRM API is our open API. It lets you connect OnePageCRM to apps and software we're not yet integrated with, or build something of your own on top of the CRM.
It's how custom CRM integrations get built: a REST API that covers contacts, companies, deals, actions, notes, calls, and meetings, so a developer can read and update your CRM data from any other system.
Do much more with your CRM
OnePageCRM comes with a whole marketplace of ready-made integrations. The API is for everything beyond them:
Connect any app to your CRM for a more seamless experience.
Build your integration with ease using our clear documentation.
React to changes in your CRM the moment they happen, with webhooks.
At developer.onepagecrm.com. Fair warning: an API requires a level of technical knowledge, so you will need a developer or engineer for this.
Anything that needs to read or update your CRM data from outside the app. The API covers contacts, companies, deals, actions, notes, calls, and meetings, and webhooks let your code react the moment something changes in the CRM.
Honestly, yes. An API is a tool for writing code, not an app you install. If you have no developer around, our Zapier integration connects OnePageCRM to thousands of apps with no code at all.
It is. API access and webhooks come with every OnePageCRM plan.
