\n\n\n### Example Workflow - Allow transfers from specific vaults\n\nTo create an API key with the ability to transfer funds from an Anchorage Digital vaults or wallet, a permission group must first be created with the **Transfer funds** permission for the desired source vaults. Creating this permission group requires a quorum of approvals on the Anchorage Digital iOS app. Once the creation is confirmed, any number of API keys may be created with this permission group in the Anchorage Digital Web Dashboard under the API 2.0 section.\n\nTo add additional permissions to the API key, update the associated permission group through the Anchorage Digital Web Dashboard. To revoke any permissions, the individual API key may be revoked, or the permission group may be updated or deleted to remove Transfer access.\n\n## API Keys\n\nAll API requests must be made over HTTPS and must include authentication using the following scheme.\n\n\n\n### Generating an API Key\n\nIn order to make a valid API request, you must first create an API key. API keys can be created and managed in the Anchorage Digital Web Dashboard under the [API 2.0 tab](https://anchoragelogin.com/api). When you create an API key, there are 3 pieces of information you will need to remember:\n - API access key\n - Ed25519 public key (optional for read-only requests)\n - Ed25519 private/signing key (optional for read-only requests)\n\nYou must generate an Ed25519 signing key pair and save the public portion in the Anchorage Digital Web Dashboard when creating the API access key. The signing key pair is used for added security with sensitive requests.\n\nPlease note, Anchorage Digital cannot recover your API access key or private signing key if you forget them. You may generate a new access key and signing key at any time if you lose access.\n\n### API Key Permissions\n\nEach API key is associated with a permission group. This permission group specifies the permitted actions for all associated API keys. Read more about permission groups [here](#section/Authentication-and-Security/Permission-Groups).\n\n### Creating a request\n\nAll requests must include the `Api-Access-Key` header, which contains your API access key as a string.\n\nEndpoints that require a signature must include the `Api-Signature` and `Api-Timestamp` headers. Read more about signatures [here](#section/Authentication-and-Security/Signatures).\n\nAll request bodies must be valid JSON and have the content type `application/json`.\n\n## Request Signatures\n\nCertain endpoints require an Ed25519 signature to be provided alongside the API key. These endpoints will specify the `Api-Signature` and `Api-Timestamp` headers as additional parameters.\n\nSignatures are optional unless explicitly required, but are encouraged for all requests. If a signature is provided, it will be verified.\n\n### Signing Keys\n\nA signing key pair is generated by the user and the corresponding public key must be provided when creating an API key.\n\nWhen creating an API key, you will be prompted to provide an Ed25519 public key. You must use the associated Ed25519 signing key (private key) when creating signatures for requests from this API key.\n\nPlease note that signing keys (Ed25519 private keys) should be stored securely by the user. The signing key should only be used to derive request signatures and should never be sent in a request. Anchorage Digital will never request you share your private key.\n\n### Generating a Signing Key\n\nThe user must securely generate an Ed25519 key pair on their own hardware and retain both the public and private portions. The Anchorage Digital API accepts a 64-character (32 bytes) hex-encoded Ed25519 public key when creating an API access key.\n\n\n#### Code sample (Python)\n\n*Generate a new signing key pair*\n\n```python\n# https://pypi.org/project/PyNaCl/\n\nimport nacl\nimport nacl.signing\nimport secrets\n\nseed = secrets.token_bytes(32)\n\n# Generate a new random signing key\nsigning_key = nacl.signing.SigningKey(seed)\n\n# Obtain the hex-encoded signing key\nprint('Signing key:')\nprint(signing_key.encode().hex())\n\n# Obtain the hex-encoded verify key for the given signing key\n# Use this in the Anchorage Digital Web Dashboard when creating an API key\nprint('Public key:')\nprint(signing_key.verify_key.encode().hex())\n```\n\n\n### Signing a Request\n\nTo sign a request, generate a request signature using the Ed25519 private (signing) key and provide it alongside the request in the `Api-Signature` header.\n\nTo create a request signature, first concatenate the `timestamp`, `method`, `request path`, and `body` into a string. Then, create a signature of this message using the Ed25519 private key and hex-encode the output. Use this value as the `Api-Signature` header and use the `timestamp` value as the `Api-Timestamp` header.\n\n- The `method` is an uppercase HTTP method (ex. `GET`, `POST`, `DELETE`)\n- The `request path` should contain all query parameters (ex. `/v2/transfers?foo=bar&baz=bang`)\n- The `body` is a stringified HTTP request body\n- The `body` should be omitted if the request does not contain a body (ex. a `GET` or `DELETE` request)\n- The `timestamp` is the same as the `Api-Timestamp` header\n- The `timestamp` is a number of seconds since the Unix Epoch in UTC, and must be within one minute of the API service's time when the request is received\n\n### Reference signature\n\nTo verify your signature generation code is correct, generate a signature for the following request and timestamp using the provided signing key. If the generated signature matches the signature below, your signature generation code is correct.\n\n\n\n \n | Timestamp | \n 1577880000 | \n
