The "Inject into" field in the pagination form of Airbyte's Connector Builder UI is used to specify where in the HTTP request a component's value should be injected. The "body_data" option is used when you want to inject the value into a form-encoded request body. However, based on the provided extracts, there isn't a specific example of using "body_data" for injecting a value into the request body, specifically into "variables['after']". The closest example we have is for the "request_parameter" and "header" options. For instance, in the case of the [Prestashop API](
https://devdocs.prestashop-project.org/8/webservice/cheat-sheet/#list-options), you can use the
next_page_token
variable to configure a query parameter with key
limit
and value
{{ next_page_token['next_page_token'] or '0' }},50
to inject the offset from the pagination strategy and a hardcoded limit of 50 into the same parameter. For more specific guidance on using "body_data" with "variables['after']", you may need to refer to the detailed documentation or seek assistance from the Airbyte community or support channels.
