Title: API credentials Last modified: November 3, 2017 --- # API credentials * Resolved [zigotic](https://wordpress.org/support/users/zigotic/) * (@zigotic) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/) * Hi guys, * I have been trying to setup my paypal express but when I save the credentials it shows this notification There is a problem with PayPal. **Your API credentials may be incorrect. Please update your API credentials.** [Learn more.](https://docs.woocommerce.com/document/subscriptions-canceled-suspended-paypal/#section-2). * I have checked the credentials over and over and with PayPal integration peps as well and they are correct. The API is signature not certificate… I have a woocommerce membership and woocomerce subscription plugins both plugins are up to date and work perfectly fine with stripe but can’t seem to get it to work with Paaypal express. Do I have to get a paypal Pro? Thank you in advance for all your help 😀 Viewing 15 replies - 1 through 15 (of 19 total) 1 [2](https://wordpress.org/support/topic/api-credentials/page/2/?output_format=md) [→](https://wordpress.org/support/topic/api-credentials/page/2/?output_format=md) * Plugin Contributor [angelleyesupport](https://wordpress.org/support/users/angelleyesupport/) * (@angelleyesupport) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9656409) * Hi [@zigotic](https://wordpress.org/support/users/zigotic/), I’m sorry for the delay in response, We have not received any reports for this so need to check why you are seeing this, I will discuss this with our senior personnel, You will receive a response soon.

USER, PASS, and SIG? * Thread Starter [zigotic](https://wordpress.org/support/users/zigotic/) * (@zigotic) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9694613) * Hi Guys, the error now is: PayPal Express Checkout Billing Agreements / Reference Transactions require specific approval by PayPal. Please contact PayPal to enable this feature before using it on your site. * I’ve verified my credentials and if my billing agreement is approved with PayPal and they said it is. Any help will be appreciated. * Plugin Contributor [angelleyesupport](https://wordpress.org/support/users/angelleyesupport/) * (@angelleyesupport) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9696092) * [@zigotic](https://wordpress.org/support/users/zigotic/), If you are still seeing that notice on your dashboard then this simply means that it’s not yet enabled. Can you check if you have LIVE api’s filled in or still using the SANDBOX MODE? If so, then can you turn on LIVE and see if that notice goes away? * Thread Starter [zigotic](https://wordpress.org/support/users/zigotic/) * (@zigotic) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9697376) * Thank you Oliver, I have contacted PayPal and they insist it’s been enabled in the account 🙁 . I have checked and it is the live API signature info, the issue is with recirring payment it seems, please help 😀 * Plugin Contributor [angelleye](https://wordpress.org/support/users/angelleye/) * (@angelleye) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9697822) * [@zigotic](https://wordpress.org/support/users/zigotic/), That notice you are seeing isn’t an error, it’s simply a notice informing you that you need to make sure Billing Agreements are enabled on your account before you start using token payments / reference transactions with Express Checkout. * If you’ve already confirmed that this is indeed active on your account then you can simply dismiss the notice in your admin panel. * Thread Starter [zigotic](https://wordpress.org/support/users/zigotic/) * (@zigotic) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9702247) * Thank you Oliver the problem is Stripe is processing the woocommerce subscriptions to the membership but PayPal is not it is charging but its not converting the customer in to a subscriber it’s like its not communicating in that regard it is processing fine the purchase of the product but not the subscription. Thank you in advance for all your help! * Thread Starter [zigotic](https://wordpress.org/support/users/zigotic/) * (@zigotic) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9702530) * I saw something about the SALT settings could you please elaborate so I can try that: * [@angelleye](https://wordpress.org/support/users/angelleye/) I’ve changed the SALT value and I still have this PayPal error. * Plugin Contributor [angelleye](https://wordpress.org/support/users/angelleye/) * (@angelleye) * [8 years, 6 months ago](https://wordpress.org/support/topic/api-credentials/#post-9709737) * I’m a little confused at this point. If your API credentials aren’t working properly, then of course the subscription isn’t going to work. So if you’re having issues with SALT and the API credentials not working, then we need to get that resolved and that should fix the rest. So is that the issue you’re still having at this point? The PayPal API is returning an error that your credentials are wrong? What’s the exact error code and message you’re getting from the PayPal response? You can see this in the logs (assuming you have logging enabled..??) * [luiseduardops](https://wordpress.org/support/users/luiseduardops/) * (@luiseduardops) * [8 years, 5 months ago](https://wordpress.org/support/topic/api-credentials/#post-9817928) * Someone can tell me what to do to solve it? “Your API credentials may be incorrect.
