I want to set a unique alphanumeric name to my campaign to retrieve it later from that name.
I use to set Headers => 'X-Mailjet-Campaign' but now i am using the API and can't make it work.
And API doc doesn't help at all cause there is no exemple given.
Does anyone know how i can set this CustomName value ?
I tried CampaignID And CampaignALT during my post on "CampaignDraft/Create" but none is working (it tells me this is not integer).
