+# Cobuild guidance
+
+Role-specific behavior:
+- `input_A_role` supplies one API call per row and the column values available to request templates.
+- `api_output` collects the response rows extracted from those calls and any paginated responses.
+
+Request behavior:
+- Columns selected in `parameter_columns` become `{{column_name}}` template variables across the URL, headers, query parameters, body, and pagination settings; `parameter_renamings` changes their template names.
+- `should_use_user_secrets=true` also exposes the current user's Profile > My account > Other credentials as template variables.
+- `body_format=RAW` uses `text_body`; `FORM_DATA` and `MULTIPART_FORM_DATA` use `key_value_body`.
+- `auth_type=null` selects the generic `credential` preset path; each secure authentication type selects its corresponding preset field.
+- For API-key presets, API Connect automatically injects the key into either a request header or query parameter, as configured by the user in the preset.
+
+Response extraction:
+- Use the dot-separated `extraction_key` when response rows are nested under a JSON path.
+- Keep `raw_output=true` when each response item should be preserved as raw JSON instead of flattened into columns.
+
+Pagination:
+- Select the pagination mechanism from the target API's documentation; do not infer one from the endpoint shape.
+- For next-page pagination, `next_page_url_key` is the dot-separated response path containing the following request URL. When that URL is relative, enable `is_next_page_url_relative` and provide `next_page_url_base`.
+- Page pagination requires `extraction_key` so the recipe can locate and count the returned data array.
+- For offset and page pagination, `skip_key` is the query parameter carrying the next offset or page number.
