Get DSA recommendations

Returns Meta's suggested beneficiary/payor names for an ad account, derived by Meta from the account's recent activity. Useful for prefilling `dsaBeneficiary`/`dsaPayor` inputs, or the defaults sent to `PATCH /v1/ads/accounts`, in your own UI. Meta returns a single flat list. Entries are not labeled as beneficiary or payor, and since these are legal disclosures Zernio never applies them automatically: let your user pick the right entity. The list may be empty for accounts with little activity. Meta accounts only.

Assign a user to a Page

Gives a person of the portfolio tasks on a Page the portfolio owns or was granted as a partner. Meta does not assign partner admins automatically, so after an owner shares a Page the partner calls this for the people whose tokens will advertise for it. `ADVERTISE` is what ad creation needs. Assigning an already assigned user replaces their task set.

accountId*string

Zernio SocialAccount id used to resolve the Meta token.

adAccountId*string

Meta ad account id (act_).

userId*string

Business-scoped user id from GET /v1/ads/businesses/users.
