Authentication

Basis Theory uses API keys to allow access to the API.

Basis Theory requires the API key to be included in all API requests to the server in a header that looks like the following:

BT-API-KEY: <API_KEY>

You must replace <API_KEY> with your API key supplied when you created an Application.

Request

cURL

curl "https://api.basistheory.com" \
  -H "BT-API-KEY: <API_KEY>"

Node

import { BasisTheoryClient, BasisTheory } from "@basis-theory/node-sdk";

const client = new BasisTheoryClient({ apiKey: "<API_KEY>" });

JavaScript (legacy)

import { BasisTheory } from "@basis-theory/basis-theory-js";

// at instance
const bt = await new BasisTheory().init("<MANAGEMENT_API_KEY>");

// per call
const bt = await new BasisTheory().init();

const applications = await bt.applications.list(
  {},
  {
    apiKey: "<MANAGEMENT_API_KEY>",
  }
);
