The non-interactive login method for the Betfair Exchange API requires that you create and upload a self-signed certificate which will be used, alongside your username and password to authenticate your credentials and generate a session token.
For the purposes of this guide, we have used OpenSSL to generate this client, details of which can be found at http://www.openssl.org/
2 Step Authentication With Non Interactive Login
Using 2 Step Authentication to secure your account for website logins will have no impact on your use of the non-interactive login method and vice versa.
Getting Started
There are a couple of steps required before we can actually log in:
- Create a self-signed certificate
- Link the certificate to your Betfair account
Creating a Self Signed Certificate
The Betfair Exchange API requires that a 1024-bit or 2048-bit RSA certificate be used. We are using OpenSSL in the below example but there are other ways of doing this, including using a UI-based interface such as XCA as covered in the Certificate Generation With XCA tutorial.
Create a public/private RSA key pair using openssl
openssl genrsa -out client-2048.key 2048
Update or Create the openssl configuration file (openssl.cnf) for OpenSSL to override some of the default settings:
[ ssl_client ] basicConstraints = CA:FALSE nsCertType = client keyUsage = digitalSignature, keyEncipherment extendedKeyUsage = clientAuth
In Windows, the config file is located in the installation directory of OpenSSL
In Linux distributions, the config file is located at /usr/lib/ssl/openssl.cnf or /etc/ssl/openssl.cnf
Create a certificate signing request (CSR).
openssl req -new -config openssl.cnf -key client-2048.key -out client-2048.csr Country Name (2 letter code) [AU]:GB State or Province Name (full name) [Some-State]:London Locality Name (eg, city) []:London Organization Name (eg, company) [Internet Widgits Pty Ltd]:yourcompany.com Organizational Unit Name (eg, section) []:Security Team Common Name (e.g. server FQDN or YOUR name) []:Test API-NG Certificate Email Address []:my.name@mydomain.com Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []:
Self-sign the certificate request to create a certificate
openssl x509 -req -days 365 -in client-2048.csr -signkey client-2048.key -out client-2048.crt -extfile openssl.cnf -extensions ssl_client
Linking the Certificate to Your Betfair Account
The previous steps should have created the following files:
File name | Description |
client-2048.key | The private key. This file is needed in order to use the certificate and should be protected and shouldn’t be shared with anyone. |
client-2048.csr | A certificate signing request. This file is no longer needed and can be deleted. |
client-2048.crt | The certificate. This file is not sensitive in security terms and can be shared with anyone. |
Before you login using the certificate, it must be attached to your Betfair account, as follows:
- Log in to your Betfair account through betfair.com. Paste the following URL into the address bar of your browser
- Navigate to https://myaccount.betfair.com/accountdetails/mysecurity?showAPI=1 - Note: Please use https://myaccount.betfair.it/accountdetails/mysecurity?showAPI=1 for the Italian Exchange or the endpoint relevant to your own jurisdiction. See the URL Definition section for more details
- Scroll to the section titled “Automated Betting Program Access” and click 'Edit'
- Click on “Browse” and then locate and select the file client-2048.crt created above.
- Click on the “Upload Certificate” button.
Scroll down to the “Automated Betting Program Access” section if required and the certificate details should be shown. You should now be able to log in to your Betfair account using the Betfair API endpoint.
Note on File Formats
Some systems require that client certificates are in a different format to the ones we’ve created. The two most common formats are (a) PEM format key and certificate in a single file and (b) PKCS#12 format file. .NET applications require a PKCS#12 format file.
To create a PEM format file that contains both the private key and the certificate you can use the following command:
cat client-2048.crt client-2048.key > client-2048.pem
Create the PKCS#12 format using crt and key
openssl pkcs12 -export -in client-2048.crt -inkey client-2048.key -out client-2048.p12
Don't circulate the key, PEM file or PCKS#12 format files as these files are security sensitive
Details of a Login Request
A login request can now be made as follows:
- Submit a HTTP “POST” request to: https://identitysso-cert.betfair.com/api/certlogin
- As part of the SSL connection, the certificate created previously must be supplied.
- Include a custom Header called “X-Application” with a value that identifies your application. The value is not validated and is only used to help with troubleshooting and diagnosing any problems.
- Ensure the POST’s Content-Type is “application/x-www-form-urlencoded” rather than MIME attachment encoded.
- As part of the POST body include two parameters “username” and “password” which should have the relevant username/password for your account.You should ensure that your username and password values are encoded before being sent to the API; if your password contains special characters and isn't encoded, the login request will fail with CERT_AUTH_REQUIRED/INVALID_PASSWORD

Sample curl command to test the non-interactive login
Using the below curl command, you should insert your own Betfair username and password. Please note: You must also specify the full file path that contains your client certificate and key.
curl -v -q -k --cert client-2048.crt --key client-2048.key 'https://identitysso-cert.betfair.com/api/certlogin' -H 'X-Application:{{appId}}' --data-urlencode 'username={{username}}' --data-urlencode 'password={{password}}' Response should be {"sessionToken":"Zx8i4oigut5nc+l4L8qFb0DSxG+mwLn2t0AMGFxjrMJI=","loginStatus":"SUCCESS"}
Note on Using Curl with Windows
Since curl is not native to Windows, the curl command may return an error.
If that happens, try using the Invoke-RestMethod by creating a .pfx file:
openssl pkcs12 -export -out client.pfx -inkey client-2048.key -in client-2048.crt
You will be prompted to enter a password. Enter it below in the place of {{pfxPassword}}. You’ll also need to replace {{appId}}, {{username}}, and {{accountPassword}} with yourApplication Key (appid), the username for your Betfair account, and the password to your Betfair account accordingly.
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" $headers.Add("X-Application", "{{appId}}") $headers.Add("Content-Type", "application/x-www-form-urlencoded") $userName = [uri]::EscapeDataString("{{username}}") $password = [uri]::EscapeDataString("{{accountPassword}}") $body = "username=" + $userName + "&password=" + $password $pfxPath = ".\client.pfx" $cert = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2($pfxPath, "{{pfxPassword}}") $response = Invoke-RestMethod "https://identitysso-cert.betfair.com/api/certlogin" -Certificate $cert -Method "POST" -Headers $headers -Body $body $response | ConvertTo-Json
Postman request to test the Non-Interactive login
To test the non-interactive login using Postman, you must first download Postman via https://www.postman.com/
The following instructions show you add to add the certificate and key file before making the login request:

2. Insert the endpoint URL (e.g. https://identitysso-cert.betfair.com/api/certlogin) and the request headers
3. Insert the request body as shown below:
4. Perform the call by clicking Send button.
