What is the Lifeditt API?

The Lifeditt API allowsyou to build software in your desired coding language and connect it to Lifeditt's 'people data'.

Give me an example

Connect Lifeditt's API to your augmented reality glasses and look at the houses around you. We will return the people data on the houses around you (such as who lives there) based on your longitude and latitude and direction faced.

  • Augmented Reality
  • Multiple coding languages
  • Low rates
  • Data by permission

Find users with the same interests

Do you have a target market for your games or app but can't reach them. Connect into the Lifeditt API and it will suggest to you users based on your criteria and current users.

API Conventions

  • API versioning is handled using a major version number in the URL, e.g. /api/v1/endpoint.

  • /something is equivalent to /something/.

  • URL paths, URL query parameter names, and JSON field names are case sensitive.

  • URL paths use lower case, with dashes separating words.

  • Query parameters and JSON fields use lower case, with underscores separating words.

  • The HTTP status indicates whether an operation failed or succeeded, with extra information included in the HTTP response body.

  • All APIs return standard error code formats.

  • Unexpected query parameters are ignored.

  • Unexpected JSON fields in the request body are ignored.

  • The JSON number type is bounded to a signed 32-bit integer.


  • To authenticate with the APIs, specify the “Authorization” header with each request. The value of the Authorization header must be a valid API key or basic auth with the API key as username and an empty password.

  • Administrators can generate an API key. Please take care to record and safeguard your API keys at all times. You cannot retrieve an API key after it has been created.

  • For examples of supplying the Authorization header, refer to the cURL example below or any of the individual API request examples.

API examples

Lifeditt Enterprise customers should make sure to change the API endpoint domain in all the example calls to the domain for their specific environment.

Note: Lifeditt Enterprise customers will need to change the endpoint in the URL field for each call

Using cURL

If you are using cURL to call the API, you must include the resource URI in quotes when you pass in multiple query parameters separated by an &.

For example:

curl -v \ -H "Content-Type: application/json" \ -H "Authorization: 14ac5499cfdd2bb2859e4476d2e5b1d2bad079bf" \ -X GET "https://api.lifeditt.com/api/v1/metrics/deliverability/aggregate?type=testjob&from=2014-01-23T14:00&metrics=sex,age,relationship&timezone=America%2FNew_York&to=2014-06-23T15:50"


curl -v \ -H "Content-Type: application/json" \ -u <'APIKey'>: \ -X GET "https://api.lifeditt.com/api/v1/metrics/deliverability/aggregate?type=testjob&from=2014-01-23T14:00&metrics=sex,age,relationship&timezone=America%2FNew_York&to=2014-06-23T15:50"

Rate Limiting

Note: To prevent abuse, our servers enforce request rate limiting, which may trigger responses with HTTP status code 429.

Lifeditt implements rate limiting on the following API endpoints:

  • /api/v1/message-events

  • /api/v1/metrics/*

The limits imposed here are dynamic but as a general rule, polling these endpoints more than once in 2 minutes may encounter rate limiting and a 429 status code.

Alternatives To Polling: For some common use cases, the Lifeditt API offers more efficient alternatives to polling, especially of the message events endpoint. For instance, A single call to the metrics deliverability summary endpoint offers a summary of deliveries, bounces, opens, clicks and more for some time period. If your application requires low latency access to each message event, using a webhook-based process will be more efficient than polling message events and will avoid rate limiting.

Sandbox Domain Limits: If you use the sandbox domain for testing you are limited to 5 requests for the lifetime of your Lifeditt account.

Account Suspension

If your account has been suspended due to concern about a possible violation of our Data Policy please reply to the email you should have received from compliance@lifeditt.com. If you have not received an email, please write to compliance@lifeditt.com, ideally from the email address you used to sign up, including your Account ID, Company Name (if you set one), and Username which you can find under Account > Profile in our app UI.


When you make an API call you may receive an error message in response. Either there is something wrong with your request or something went wrong on our end. Errors respond with an error code and JSON that contains a more precise message, description and API code.

Example Error

422 Unprocessable Entity
{"{"errors": [{"message": "required field is missing","description": "content object or template_id required","code": "1400"}]}}

Error Table

Code Status Name Description Suggested Action
400 Bad Request There is a problem with your request. Check your request follows the API documentation and uses correct syntax.
401 Unauthorized You don'''t have the needed authorization to make the request. Make sure you are using a valid API key with the necessary permissions for your request.
403 Forbidden The server understood the request but refused to fulfill it. See if your Lifeditt plan includes the resource you are requesting and your API key has the necessary premissions.
404 Not Found The server couldn't find the requested file. Change your request URL to match a valid API endpoint.
405 Method Not Allowed The resource does not have the specified method. (e.g. PUT on transmissions) Change the method to follow the documentation for the resource.
409 Conflict A conflict arose from your request. (e.g. user already exists with that email) Modify the payload to clear the conflict.
415 Unsupported Media Type The request is not in a supported format. Check that your Content-Type header is a supported type and that your request adheres to the documentation.
422 Unprocessable Entity The request was syntactically correct but failed due to semantic errors. Make sure that your request includes all of the required fields and your data is valid.
429 Exceed Sending Limit You sent too many requests in a given time period. Check that you are with in the limits of your Lifeditt plan. (If you are using the sandbox domain you'll need to add a sending domain to continue.)
500 Internal Server Error Something went wrong on our end. Try the request again later. If the error does not resolve, contact support.
503 Service Unavailable We are experiencing higher than normal levels of traffic. Try the request again.
