# Create entity evidence

**POST** `/entities/{entity_id}/evidence`

Add evidence to an entity. Supports file, signature, and third-party JSON evidence — if your KYC provider sends you a JSON blob, pass it directly in `data` with `third_party_json` as the `evidence_type`. A single submission can cover several purposes at once: Column creates one evidence record per entry in `purposes`, all referencing the same underlying document or data.

### Path Parameters

- `entity_id` `string` _(required)_ — Unique identifier for the entity.

### Body Parameters

- `data` `object` — Structured data associated with the evidence, as a JSON object. The shape of this object depends on the evidence type.
- `description` `string` — A description of the evidence.
- `evidence_type` `string` _(required)_ — The type of evidence to submit.
- `purposes` `array of enums` _(required)_ — The purposes of the evidence submission. Column creates one evidence record per purpose, all referencing the same document/data. Use `cardholder_agreement` for cardholder agreements collected for card programs.
  Possible values: `proof_of_address`, `business_formation`, `identity_verification`, `tax_id_confirmation`, `active_status_certificate`, `signed_account_agreement`, `cardholder_agreement`, `attestation_control_person`, `attestation_beneficial_ownership`, `attestation_account_info_truth`, `attestation_terms_of_service`, `ofac_screening`, `adverse_media_screening`, `pep_screening`, `complete_customer_file`, `irs_form_ss4`, `irs_form_990`, `nonprofit_other_evidence`, `edd`, `attestation_privacy_policy`
