Returns a page of the attached integrations of the customer account with the given external ID, newest first. Deleted integrations are not included. The response has no total count: request the next page until a page has fewer than per_page integrations. External IDs in the path may contain dots (for example refine.com). Do not add a format suffix such as .json to the path: it would be read as part of the ID. Requires the integrations_read permission.
