# Create evidence with file upload

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

Create evidence with direct file upload in a single request.

**Content-Type**: `multipart/form-data`

### Path Parameters

- `entity_id` `string` _(required)_ — ID of the entity.

### Body Parameters

- `description` `string` — Description of the evidence.
- `document_type` `string` _(required)_ — Type of document being uploaded.
- `evidence_type` `string` _(required)_ — Type of evidence. Must be `file` for file uploads. Available types: `file`, `third_party_json`, `signature`.
- `file` `file` _(required)_ — The document file to upload. Maximum size: `5GB`. Supported formats: `PDF`, `JPG`, `PNG`, `TIFF`.
- `purposes` `string` _(required)_ — Purposes of the evidence. Because multipart form fields are strings, pass them as a single comma-separated value (e.g. `proof_of_address,business_formation`); the JSON endpoint accepts a `purposes` array instead. Column creates one evidence record per purpose, all referencing the same uploaded file.
  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`
