laposta_add_member

WRITE: add one email address to a mailing list (subscribe). On a double opt-in list Laposta sends the confirmation email to that address. The address must have given consent. With upsert, an existing active member's fields are overwritten; an unsubscribed member is re-activated unless suppress_reactivation is set.

Discovered
laposta_create_campaign

WRITE: create a new regular campaign (a draft: it is NOT filled, scheduled or sent). Fill it with laposta_set_campaign_content, check it with laposta_send_test_email and send it in the Laposta app. The from_email must be an approved sender address of the account.

Discovered
laposta_get_campaign

Get one campaign: name, subject, preview text, sender, reply-to, recipients, delivery moments and web version URL.

Discovered
laposta_get_campaign_content

Get the plain-text content of a campaign (and its import_url if it was imported). Set include_html to also get the full HTML (large).

Discovered
laposta_get_campaign_history

Result figures of one campaign: sent, accepted, unique opens and clicks, bounces, complaints, unsubscribes and their ratios.

List the segments of a mailing list (a segment id can be a campaign recipient together with its list).

Discovered
laposta_set_campaign_content

Discovered
laposta_update_member

WRITE: change a member's custom field values and/or email address, or unsubscribe the member (state: unsubscribed). Only the fields you pass change. Re-subscribing a person is not offered here: do it in the Laposta app or with laposta_add_member upsert only when they asked for it.
