  title: EmailOctopus v2 Field API
  description: "# Introduction\n\nThe EmailOctopus API allows you to manage resources and perform actions within the platform programmatically. You'll need to <a href=\"https://emailoctopus.com/account/sign-up\" target=\"_blank\">create an account</a> before using the API, if you don't already have one.\n\nThe API is designed around <a href=\"https://en.wikipedia.org/wiki/REST\" target=\"_blank\">REST</a> principles. It has a predictable URL structure based on resources, accepts <a href=\"https://www.json.org/json-en.html\" target=\"_blank\">JSON-encoded</a> request bodies, returns JSON-encoded responses and uses standard HTTP response codes, authentication and verbs.\n\nThe base URL for the API is https://api.emailoctopus.com.\n\n# Authentication\nTo use the API, you'll need to generate an API key. You can do this in your <a href=\"https://emailoctopus.com/developer/api-keys\" target=\"_blank\">account settings</a>. If you have an API key created prior to the release of API v2 (labelled 'legacy') you'll need to generate a new API key. New API keys are compatible with all versions of the API.\n\nThe API uses bearer authentication to authenticate requests. Authenticate your request by including the following header:\n```\nAuthorization: Bearer {token}\n```\n\nFor example, using curl:\n```\ncurl https://api.emailoctopus.com/lists/ -H \"Authorization: Bearer {token}\"\n```\n\nIf you see a JSON-formatted response with your list details, that's great! That means you can connect to the API, and your authentication token works.\n\nIf you encounter a JSON error response, refer to the `type` field for a link to detailed documentation. For non-JSON errors, the request likely didn't reach the server. In that case, double-check the URL and verify that your request is correctly formatted.\n\n# Rate limiting\nRequests to the API are subject to a rate limit, which is implemented using the <a href=\"https://en.wikipedia.org/wiki/Token_bucket\" target=\"_blank\">token bucket algorithm</a>. Each request consumes one token and your bucket holds up to 100 tokens. Tokens are replenished at a rate of 10 per second. To check your remaining tokens, refer to the `X-RateLimiting-Remaining` header in the response.\n\nThis system enables a steady request rate of up to 10 per second or a burst of up to 100 requests in a single instance if needed.\n\nIf your account exceeds the rate limit, the request will return a [429 HTTP status code](https://emailoctopus.com/api-documentation/v2#too-many-requests).\n\n# Pagination\nWhen you request a collection of entities, such as contacts belonging to a list, the data will be paginated rather than returned all at once. Each response will contain a maximum of 100 results in the `data` attribute.\n\nPagination information is included in the response `paging` attribute. This data will contain `next` attributes, with a URL and a `starting_after` cursor. The cursor serves as a link to the next page. You can use the cursor as a `starting_after` query string parameter to navigate to the next page or follow the provided URL in the JSON structure.\n\nHere's an example of what the `paging` attribute looks like:\n```\n\"paging\": {\n    \"next\": {\n        \"url\": \"https://api.emailoctopus.com/lists/{list_id}/contacts?starting_after=WyIyMDI0LTEyLTA3VDE1OjAzOjAxKzAwOjAwIiwiNDYzN2RmYTAtYjZmMC0xMWVmLWFjZDYtZjU5YjA4MDFlMjBkIl0&limit=100\",\n        \"starting_after\": \"WyIyMDI0LTEyLTA3VDE1OjAzOjAxKzAwOjAwIiwiNDYzN2RmYTAtYjZmMC0xMWVmLWFjZDYtZjU5YjA4MDFlMjBkIl0\"\n    }\n }\n```\nYou can add the cursor to your request URL by including the `starting_after` query string parameter, like this:\n```\nhttps://api.emailoctopus.com/lists/{list_id}/contacts?starting_after=WyIyMDI0LTEyLTA3VDE1OjAzOjAxKzAwOjAwIiwiNDYzN2RmYTAtYjZmMC0xMWVmLWFjZDYtZjU5YjA4MDFlMjBkIl0\n```\n\nThe cursor should always be provided exactly as it was returned in a previous request. Avoid deconstructing the cursor and relying on any data inside it, as the implementation of the cursor is subject to change.\n\n# Errors\nError are returned in a standardised format following <a href=\"https://datatracker.ietf.org/doc/html/rfc7807\" target=\"_blank\">RFC 7807</a>. For example:\n\n```\n{\n    \"title\": \"An error occurred.\",\n    \"detail\": \"Bad request.\",\n    \"status\": 400,\n    \"type\": \"https://emailoctopus.com/api-documentation/v2#bad-request\"\n}\n```\n\nYou can use the `type` value to navigate to the documentation for more details about the specific error.\n\nYou may also encounter validation errors, which will return a 422 HTTP status code and a payload formatted according to <a href=\"https://www.rfc-editor.org/rfc/rfc9457.html\" target=\"_blank\">RFC 9457</a>.\n```\n{\n    \"title\": \"An error occurred.\",\n    \"detail\": \"Unprocessable content.\",\n    \"status\": 422,\n    \"errors\": [\n         {\n            \"detail\": \"This value should not be blank.\",\n            \"pointer\": \"/email_address\"\n         }\n    ],\n    \"type\": \"https://emailoctopus.com/api-documentation/v2#unprocessable-content\"\n}\n```\n\nIn the following sections, you can find more information about each type of error.\n\n## access-denied\nYou do not have permission to access the requested entity, such as trying to get the contacts in a list belonging to another account.\n\nCheck that the API key you're using belongs to the account you're trying to access data in. You can verify this by navigating to the account's <a href=\"https://emailoctopus.com/developer/api-keys\" target=\"_blank\">API keys</a> and checking there's a key ending in the same four characters.\n\n## already-exists\nYou are attempting to create an entity that already exists, such as creating a tag on a list that already contains that tag, or adding a contact to a list that already includes that contact.\n\nYou can fix this by checking if the entity already exists before you attempt to create it. Or you may wish to handle the error gracefully in your code and update the existing resource when a duplicate is spotted.\n\nSome endpoints, such as the [create or update contact](#tag/Contact/operation/api_lists_list_idcontacts_put) endpoint, support an *upsert* operation. An upsert allows you to either update the entity if it exists or create a new one if it doesn't. Consider using this feature where applicable.\n\n## bad-request\nThe request body is not in the format expected. Check that the request body is valid JSON.\n\n## conflict\nThis request conflicts with the system state. <a href=\"https://help.emailoctopus.com/category/20-getting-in-touch\" target=\"_blank\">Get in touch</a> if you require further assistance.\n\n## internal-error\nThis error is returned when the API encounters an unexpected condition or an internal issue on the server. If you receive this error, it is probably not an issue with your request.\n\nIn some cases, retrying the request after some time may resolve the issue. We'll always be notified of the error via our internal tracking tools, but if the problem persists, <a href=\"https://help.emailoctopus.com/category/20-getting-in-touch\" target=\"_blank\">get in touch</a> with details about the error and we'll investigate.\n\n## not-found\nThe resource you're trying to access or modify could not be found. This error is typically caused by using an invalid or incorrect identifier, such as a list ID or contact ID that doesn't exist in your account.\n\nDouble-check the resource identifiers you're using in your request, and ensure they match the actual resources in your EmailOctopus account.\n\n## out-of-limits\nExecuting this operation would cause you to exceed your plan limits. See our <a href=\"https://emailoctopus.com/pricing#comparison\" target=\"_blank\">pricing comparison</a> for further details on these limits.\n\n## unauthorized\nThe API key provided in the request is either invalid or missing. Ensure that you're using the correct API key and that it is included in the request header as shown in the [authentication section](/api-documentation/v2#section/Authentication).\n\n## unprocessable-content\nThe JSON payload in your request body doesn't meet the required criteria. Check the errors attribute for details on the specific issues. It will include a pointer to the problematic attribute and an error description.\n\n## unsupported-media-type\nWhen making requests that require a JSON payload in the body, you must specify a `Content-Type` of `application/json`.\n\n## too-many-requests\nYour account has exceeded the rate limit. You can use the `X-RateLimit-Retry-After` header to determine when to make another request. See the [rate limiting section](/api-documentation/v2#section/Rate-limiting) section for further details.\n\n## method-not-allowed\nThe HTTP method used in your request is not supported for the endpoint you are trying to access. For example, attempting to use a POST method on an endpoint that only supports GET.\n\nCheck the API documentation for the correct methods allowed for each endpoint. Ensure your request uses one of the supported methods (e.g., GET, POST, PUT, DELETE) for the specific operation you want to perform.\n"
