Square up checkout integration with laravel

Hello, i am new to square up and i need help on how to integrate square up checkout in a laravel project. I’ve tried to run composer require square/connect as it is in one the github accounts but seems the package has been retired, how can i go about it to integrate square up checkout in a laravel project.

:wave: At this time we don’t have an example in Laravel. We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. What issues are you running into when trying to integrate the Web Payments SDK? :slightly_smiling_face:

i await your response. thanks

If you remove $orderId from the payment request does it work as expected? It looks like you’re generating a random order_id instead of using the one that we generate when calling CreateOrder. :slightly_smiling_face:

Still showing the same error…

i think the response should be 200 OK, why is it giving 204 no content ?

i would appreciate it, if you can give or recommend an example of how to integrate it with HTML and JavaScript not Node.Js or with HTML and PHP.

Did you succeed in implementing using Laravel? I have been trying to do it from couple of weeks and I feel lost and no progress.

No, not yet.

I’ve went through the documentation many times still the same result. Maybe there is no solution to it for now.

Is the 204 error a Square error that you’re getting back? :slightly_smiling_face:

Yes and think the response should be 200 OK

So the payment was successful? :slightly_smiling_face:

We have examples in other supported languages like PHP. :slightly_smiling_face:

The ones I’ve tried kept on giving the same error, if you don’t mind, can you recommend another PHP examples

Hi @Psimon, we don’t have any other example projects that implement payments for PHP at this time.
