Create JSON Web Tokens signed with your private key to authorize API requests.
Overview
Oct 12, 2016 Angela from the API support team walks through how to generate a public private key pair using OpenSSL and register a private application. If you want to try integrating to Xero, partner. Jun 08, 2015 'Apologies if this is mentioned elsewhere. The private key used for signing the tokens, is this the same as a private key generated using ssh-keygen?' Originally posted by @skota on ryanfitz/hapi-auth-jwt#30. Jun 08, 2015 The private key used for signing the tokens, is this the same as a private key generated using ssh-keygen? Originally posted by @skota on ryanfitz/hapi-auth-jwt#30 nelsonic added enhancement help wanted question labels Jun 8, 2015. There is a set of parties, each of whom have a public/private key. I have the public key for each of them. These parties will send me JWTs signed with their private key. I do not know which party sent the JWT, so I need to check the JWT. If the signature matches for public key #1, I know it came from party #1. Aug 05, 2016 I am using the jose-jwt library and want to create an encrypted JWT in C# using the RS256 algorithm for encryption. I have no experience with cryptography, so please excuse my ignorance. I see the following example in the docs: var paylo.
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a way to securely transmit information. The App Store Connect API requires JWTs to authorize each API request. You create the token, signing it with the private key you downloaded from App Store Connect.
To generate a signed JWT:
Create the JWT header.
Create the JWT payload.
Sign the JWT.
Include the signed JWT in the authorization header of each App Store Connect API request.
Create the JWT Header
To create a JWT to communicate with the App Store Connect API, use the following fields and values in the header:
To get your key ID, copy it from App Store Connect by logging in to App Store Connect, then:
Select Users and Access, then select the API Keys tab.
The key IDs appear in a column under the Active heading. Hover the cursor next to a key ID to display the Copy Key ID link.
Click Copy Key ID.
If you have more than one API key, use the key ID of the same private key that you use to sign the JWT.
Here's an example of a JWT header:
Create the JWT Payload
The JWT payload contains information specific to the App Store Connect APIs, such as issuer ID and expiration time. Public private key pair generation. Use the following fields and values in the JWT payload:
To get your issuer ID, log in to App Store Connect and:
Select Users and Access, then Select the API Keys tab.
The issuer ID appears near the top of the page. To copy the issuer ID, click Copy next to the ID.
Here's an example of a JWT payload:
Sign the JWT
Use the private key associated with the key ID you specified in the header to sign the token.
Regardless of the programming language you're using with the App Store Connect API, there are a variety of open source libraries available online for creating and signing JWT tokens. See JWT.io for more information.
Tip
You do not need to generate a new token for every API request. To get better performance from the App Store Connect API, reuse the same signed token for up to 20 minutes.
Include the JWT in the Request's Authorization Header
Once you have a complete and signed token, provide the token in the request's authorization header as a bearer token.
The following example shows a curl command using a bearer token. Replace the text '[signed token]' with the value of the signed token itself.

Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). The key must be kept secret from anyone who should not decrypt your data. The IV does not have to be secret, but should be changed for each session. Asymmetric algorithms require the creation of a public key and a private key. The public key can be made public to anyone, while the private key must known only by the party who will decrypt the data encrypted with the public key. This section describes how to generate and manage keys for both symmetric and asymmetric algorithms.
Symmetric Keys
The symmetric encryption classes supplied by the .NET Framework require a key and a new initialization vector (IV) to encrypt and decrypt data. Whenever you create a new instance of one of the managed symmetric cryptographic classes using the parameterless constructor, a new key and IV are automatically created. Anyone that you allow to decrypt your data must possess the same key and IV and use the same algorithm. Generally, a new key and IV should be created for every session, and neither the key nor IV should be stored for use in a later session.
To communicate a symmetric key and IV to a remote party, you would usually encrypt the symmetric key by using asymmetric encryption. Sending the key across an insecure network without encrypting it is unsafe, because anyone who intercepts the key and IV can then decrypt your data. For more information about exchanging data by using encryption, see Creating a Cryptographic Scheme.
The following example shows the creation of a new instance of the TripleDESCryptoServiceProvider class that implements the TripleDES algorithm.
When the previous code is executed, a new key and IV are generated and placed in the Key and IV properties, respectively.
Sometimes you might need to generate multiple keys. In this situation, you can create a new instance of a class that implements a symmetric algorithm and then create a new key and IV by calling the GenerateKey and GenerateIV methods. The following code example illustrates how to create new keys and IVs after a new instance of the symmetric cryptographic class has been made.
When the previous code is executed, a key and IV are generated when the new instance of TripleDESCryptoServiceProvider is made. Another key and IV are created when the GenerateKey and GenerateIV methods are called.
Asymmetric Keys
The .NET Framework provides the RSACryptoServiceProvider and DSACryptoServiceProvider classes for asymmetric encryption. These classes create a public/private key pair when you use the parameterless constructor to create a new instance. Asymmetric keys can be either stored for use in multiple sessions or generated for one session only. While the public key can be made generally available, the private key should be closely guarded.
A public/private key pair is generated whenever a new instance of an asymmetric algorithm class is created. After a new instance of the class is created, the key information can be extracted using one of two methods:
The ToXmlString method, which returns an XML representation of the key information.
The ExportParameters method, which returns an RSAParameters structure that holds the key information.
Both methods accept a Boolean value that indicates whether to return only the public key information or to return both the public-key and the private-key information. An RSACryptoServiceProvider class can be initialized to the value of an RSAParameters structure by using the ImportParameters method.

Asymmetric private keys should never be stored verbatim or in plain text on the local computer. If you need to store a private key, you should use a key container. For more on how to store a private key in a key container, see How to: Store Asymmetric Keys in a Key Container.
The following code example creates a new instance of the RSACryptoServiceProvider class, creating a public/private key pair, and saves the public key information to an RSAParameters structure.
