Call to Get all layout IDs for all senders

Hi Samira, Because Layout/Template should only be visible to their owner (except shared ones), so I'm afraid there's no direct API call retrieving layouts from all senders. But since it's account/API_KEY binded, you'd first retrieve all senders' api keys then get layout IDs for them each, in below workflow: (1) retrieve all sender list, guide here:

HTTP Request
GET /api/account/senders?from=1&to=100

HTTP Headers
Accept: application/json
Content-Type: application/json
Authorization: Basic api_key

(2)retrieve sender's api key (same Senders guide):

HTTP Request
GET /api/account/senders/{senderId}/apiKey

HTTP Headers
Accept: application/json
Content-Type: application/json
Authorization: Basic api_key

Response Payload
{
    "apiKey": "XXXXXXXXXXXXX=="
}

(3) put the sender's api key in request header and retrieve layout ids (guide here):

HTTP Request
GET /api/layouts?summary=true&from={fromPage}&to={toPage}

HTTP Headers
Accept: application/json
Content-Type: application/json
Authorization: Basic {sender_api_key}

Just note that, * "summary=true" this parameter would hide some part of the return result and reduce the response time * this call returns you all shared layouts, so there's overlaps if you did the same call to all senders. You probably want to have a filter to the return results on "sender" node and check the owner's email with the current api key's account. I understand that it's a complex workflow, so if you told me your programming language, I can create some sample code for you. Hope this could help! Duo
