Updates a template

Updates specific fields of a payin template. Scoped to the requesting client.

The update is presence-aware: an omitted field keeps its current value and an explicit null clears a nullable field. payin_data, form_customization and method_params are partial objects merged field by field; expected_payers replaces the whole list.

Expected payers can only be set on a template one of whose methods validates them: on a template that only offers co_pse the request fails with payin_expected_payers_not_supported.

method_params only takes co_pse, whose payer is the suggested payer the hosted checkout pre-fills: a complete payer replaces it, null removes it and an omitted payer keeps it. On a template that does not offer co_pse the request fails with payin_unsupported_method_params.

A template cannot be updated while still created (its Bre-B setup may be in flight), in discarded or failed state, as a consumed (paid) single-use template, or while being pruned (prune_state not null). The update is serialized with payin processing through the template lock.

Updating total_minimum_amount/total_maximum_amount may transition the template state (ready ⇄ minimum_paid, → paid, or back out of paid). The transition is included in the payin_template_updated webhook — which every successful update emits, with the previous values of the changed fields — and does NOT trigger the separate state-change webhooks.

Attributes to update the template

TypeScript Definitions

Use the request body type in TypeScript.

expected_payers?array|null

expires_at?string|null

Expiration date for the template as ISO-8601 datetime. Must be in the future; null removes the expiration.

Formatdate-time
Example"2022-01-01T01:00:00Z"

metadata?object|null

Arbitrary tenant-defined metadata.

Example{ "id": 3, "reference": 123 }

minimum_payin_amount?object|null

Minimum amount allowed in a single Payin.

nickname?string|null

Human-readable name to identify the template.

Length5 <= length <= 255
Example"string"
