Passing JSON BODY with Stripe Create Checkout Session for multiple items

Need help APIs
1

Hi everyone,

I’m trying to pass the JSON Body to create a Stripe checkout session for multiple items. I have defined my JSON Body in the API connector:

The problem is when I pass the dynamic data into these dynamic inputs, it keeps returning this error:

I’ve tried to replace the API with Pipe and it called successfully and returned a JSON that I can format successfully. I have tried many ways, remove the /n in the JSON Body, remove the space it still returns the same error.

I’m crazy with this for a few days. Please help!

Example of JSON Body I pass in:

{"custom_fields":[{"key":"firstName","type":"text","label":{"custom":"First Name","type":"custom"}},{"key":"lastName","type":"text","label":{"custom":"Last Name","type":"custom"}}],"metadata":{"KC":2,"KB":2},"line_items":[{"quantity":2,"price":"price_1OrLp5Krc3r80P9jhGoPjWD3"},{"quantity":2,"price":"price_1OrLp5Krc3r80P9jhGoPjWD3"}],"allow_promotion_codes":"true","cancel_url":"https://lyfehealth.us/version-0qvi/?transaction=1712396458917x594358496383467500","payment_intent_data":{"application_fee_amount":142.2,"transfer_data":{"destination":"acct_1NQQ80QOMUKnpu3p"}},"shipping_address_collection":{"allowed_countries":["US"]},"mode":"payment","success_url":"https://lyfehealth.us/version-0qvi/order_confirm?transaction=1712396458917x594358496383467500","shipping_options":[{"shipping_rate":"shr_1NxpIjKrc3r80P9jVym1cX2T"}],"customer":"","customer_email":"gokuxayda123@gmail.com"}```

As explained in the Stripe API docs, the Stripe API doesn’t accept JSON request bodies… only form encoded request bodies.

So you need to format the request body as query parameters

If you want to continue to use JSON at first because it’s easier to encode, you can use this plugin to convert the json to something that Stripe accept

Is there a way to pass it dynamically? My website has about 10 products at the moment, which means I have to manually create 10 line items like this?

Use the plugin… you could do it dynamicwlly even if this is querystring but adding numbering to array item is very complex. Using the plugin you encode it as json and it will do the numbering for you

But if you search forum, you will find a lot of example on how to set stripe call. This is a very popular subject…

Hey, can you please guide me on how to set the API connector to pass in the result after encoded please?

You do the encoding directly in the plugin not in API connector. The result in the plugin will go in the api connector. I’m on mobile, but will try to post a screenshot later

Yes, it can be be dynamic if you put put it as a single string in the body, and put dynamic content between <>. e.g.

mode=payment&success_url=<success_url>&cancel_url=<cancel_url>&<line_items>

For dynamic lines items, just use format as text on your list of line-items, and format each one like:

line_items[0][price_data][currency]=usd&line_items[0][price_data][product_data][name]=myProduct&line_items[0][price_data][unit_amount]=12000&line_items[0][price_data][quantity]=6

&

line_items[1][price_data][currency]=usd&line_items[1][price_data][product_data][name]=myProduct&line_items[1][price_data][unit_amount]=12000&line_items[1][price_data][quantity]=6

&

line_items[2][price_data][currency]=usd&line_items[2][price_data][product_data][name]=myProduct&line_items[2][price_data][unit_amount]=12000&line_items[2][price_data][quantity]=6

Hey @adamhholmes ,

Any clue how to populate the [number] fields without saving each to the database?

Using the plugin mentionned in another post. The plugin will add it for you…

I actually found a solution to this that doesn’t involve any plugin at all !

What i found is that Stripe only accepts application/x-www-form-urlencoded requests, which actually means that the information should in fine be in the URL of the request.

For example in your case you want the URL to be :

https://api.stripe.com/v1/checkout/sessions?line_items[0][price]=price_something&line_items[0][quantity]=x&line_items[1][price]=price_something_else&line_items[1][quantity]=y

To do this, you can construct a datatype that contains the line_items informations, for example a stripe_cart datatype that has an array field of datatype stripe_line_items. And a stripe_line_items has an ID price text field, and an index integer field (representing the 0 and 1 in the url above). If needed you can add a quantity field as well to represent x and y.

Then you need to configure your API call as follows :

And when calling it in workflows complete the parameters field like this :

NB : be sure to adapt the formulas according to your implementation of this solution (index or index-1 depends how you create them for example)

Let me know if this helps you in any way !
