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>"

JavaScript

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>",
  }
);

C#

using BasisTheory.net.Tokens;

// At service
var client = new TokenClient("<PRIVATE_API_KEY>");

// Per call
var client = new TokenClient();

await client.GetAsync(requestOptions: new RequestOptions {
  ApiKey = "<PRIVATE_API_KEY>"
});

Python

import basistheory
from basistheory.api import tokens_api

# At instance
api_client = basistheory.ApiClient(configuration=basistheory.Configuration(api_key="<PRIVATE_API_KEY>"))
client = tokens_api.TokensApi(api_client)

# Per call
client.list(request_options=basistheory.RequestOptions(api_key="<PRIVATE_API_KEY>"))
