Obtaining API Credentials

To use the PayPal APIs, you must have API credentials that identify you as a PayPal account

holder who is authorized to perform various API operations. Although you can use either an

API signature or a certificate, PayPal recommends you use a signature.

IMPORTANT:Although you have both a signature and a certificate, you cannot use both at

the same time.

Creating an API Signature

An API consists of an API username along with an associated API password and signature, all

of which are assigned by PayPal. You need to include this information whenever you execute a

PayPal API operation.

You must have a PayPal account to create a signature.

To create an API signature:

1. Log in to PayPal, then click Profile under My Account.

2. Under Account Information, click Request API Credentials.

3. Under Option 1 - PayPal API, click Set up PayPal API credentials and permissions.

4. Under Option 2, click View API Signature.

5. Save the information and click Done to complete the process.

Creating an API Certificate

Create an API certificate only if your website requires it. Typically, you want to create an API

signature for your credentials instead.

You must have a PayPal account to create an API certificate.

NOTE:The certificate for API credentials is not the same as an SSL certificate for your

website; they are not related to each other.

If you do need a certificate, follow these instructions:

1. Log in to PayPal, then click Profile under My Account.

2. Under Account Information, click Request API Credentials.

3. Under Option 1 - PayPal API, click Set up PayPal API credentials and permissions.
