Subform API

A subform is a secondary form or a table, which will enable you to include multiple line items into a primary form. They are used to associate multiple items to a single record. On a more technical perspective, subforms easily solve the need for you to establish a one-to-many relationship with data in your CRM, in which many secondary items are associated to a single primary record.
The Subform API is available only in Enterprise and above editions of Zoho CRM.

Points-to-remember

  • The parent Module API name can be acquired using the modules API.

  • The Field API names of the subform can be acquired using Fields Metadata API of the parent module.

  • The Field API names of the individual fields in a subform can be acquired using Fields Metadata API, with the request URL as "fields?module={Sub_form_api_name}".

  • A module can have a maximum of two subforms for all editions except Ultimate. The Ultimate edition can have a maximum of 5 subforms.

  • A module can have a maximum of 200 subform records with each subform having a maximum of 100 records.

  • A maximum of 5 aggregate custom fields are available for a subform.
