Create an Asset Allocation Template Assignment

post

https://live.moment-api.com/v1/allocation-template-assignment/

Assigns a published template to an account. Server-side Resolve(assigned_version, overrides) persists materialized_config. Unique on account_id. Materializes the tree on the account's sleeves in the same operation — one sleeve per funded slot created, updated, or adopted, displaced sleeves marked transitioning — reported in the response's sleeve_results; a refused push rolls the assignment back (409). If accounts gives no clear answer the assignment is kept, still assigning, and the response is 202 with it; reading the assignment by id finishes it.

201Assignment created

202The assignment is recorded, but accounts gave no clear answer on the sleeve changes. It is still assigning; reading it by id finishes it.

400Validation failed - the structured conflicts identify the failing nodes

401Unauthorized

404Template not found

409Nothing was assigned: the account already has a template, the template is archived or cannot be assigned, the account rejected the sleeve changes, or a create of this template is still being applied (change_in_flight). The response says which.

503The organization's assignments could not be reached. The write may already have landed, so a retry can answer 404 or 409.
