API

hi,

Can anyone tell me where I can find the API module, is it available in the open source version?

Thanks

There is no specific API module. The API is an integrated component of all Vtiger CRM releases, including the open-source version.

Look up the documentation ://help.vtiger.com/article/147111249-Rest-API-Manual?catid=&subid=

or this (with examples): https://blog.crm-now.de/2018/02/26/neue-api-beschreibung-und-beispiele-fuer-crm-rest-operationen/?lang=en
