The gift card to create. The type field is required for this request. The gan_source
and gan fields are included as follows:
To direct Square to generate a 16-digit GAN, omit gan_source and gan.
To provide a custom GAN, include gan_source and gan.
- For
gan_source, specify OTHER.
- For
gan, provide a custom GAN containing 8 to 20 alphanumeric characters. The GAN must be
unique for the seller and cannot start with the same bank identification number (BIN) as major
credit cards. Do not use GANs that are easy to guess (such as 12345678) because they greatly
increase the risk of fraud. It is the responsibility of the developer to ensure the security
of their custom GANs. For more information, see
Custom GANs.
To register an unused, physical gift card that the seller previously ordered from Square,
include gan and provide the GAN that is printed on the gift card.
