Please ensure you have added a passphrase on the PayFast plugin page and that this matches the passphrase set on the ‘Integration’ page, under ‘SETTINGS’ in your PayFast merchant account.
The following recommendations will assist you to choose and set an appropriate passphrase:
- Exclude any similar looking ( e.g. i, l, 1, L, o, 0, O ) or ambiguous ( { } [ ] ( ) / \ ‘ ” ` ~ , ; : . < > ) characters
- Ensure that there are no spaces saved before or after the passphrase, when saved on the plugin, as this may be add an extra invisible character in the passphrase.
