I was able to retrieve data from my webshop hosted by a 3the company. Normaly we can retrieve and upload data by API

Download = working (I retrieve some productdata)

Upload (Change a name from a product seems to be more difficult)

For upload, the server samples show this :

curl -X PATCH "http://swagger.shoptrader.com/api/v2/products/1994?token=abc" -H "accept: application/json" -H "token: abc" -H "Content-Type: application/json" -d "{\"model\":\"string\",\"sku\":\"string\",\"ean\":\"string\",\"name\":\"Test 1994\",\"description\":\"string\",\"introDescription\":\"string\",\"extraDescription\":\"string\",\"metaTitle\":\"string\",\"metaKeyword\":\"string\",\"metaDescription\":\"string\",\"quantity\":0,\"categoryId\":0,\"price\":0,\"purchasePrice\":0,\"status\":true,\"taxRate\":0,\"manufacturerId\":0,\"width\":0,\"height\":0,\"weight\":0,\"images\":[\"ImageOne\"],\"imagesAlt\":[\"ImageOneAlt\"],\"resources\":[{\"resourceKey\":\"key\",\"resourceValue\":\"value\",\"resourceType\":\"type\"}]}"

and there is

Request Url :

http://swagger.shoptrader.com/api/v2/pr ... ?token=abc

For retrieve we put : "https://swagger.shoptrader.com/api/v2/products?limit=100&token=abc" and this gives resulting data to retrieve

Now for upload/edit online, how does the program need to get the command ? The request Url = not having all the data i thing

I found a testing server from swagger, and there the folowing is working :

curl -X 'PUT' \
'https://petstore.swagger.io/v2/pet' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"id": 666,
"name": "Noyca",
"status": "available"
}'

the request url :

https://petstore.swagger.io/v2/pet

I get a Response on the demo server :

200 so it is done ok and
{
"id": 666,
"name": "Noyca",
"photoUrls": [],
"tags": [],
"status": "available"
}

The demo server : https://editor.swagger.io/?_ga=2.123072 ... 1621675979

This is changing the content of the online database. It is 1 field to update, so if I can get this to work from FW i think I can get it to work for my shop as well.

I've seen several postings on cUrl, but non I get working for this code.

In fact,

I'm getting close.

I found a program that converts cUrl code to programming code.

Can any of these help finding a FW solution ?

So

curl -X 'PUT' \
'https://petstore.swagger.io/v2/pet' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"id": 666,
"name": "Troy",
"status": "available"
}'

Yes, This will update the data on the test server.

On my server it also changes the data, but always there is a new record created ?

I put some code I was testing. Data is written, but also every time a new record.

The ID of the product = 2062 and is put in the url.

I have tried also 'PUT' and 'PATCH' have been reading about it, but the I get return code 404 = not found error

Sorry, But this was not working.

It also needs a extra ch file (found) and i think 2 libs to link.

POST is for adding a new pet and PUT is for modifying an existing one.
Error 404 means the id you are trying to modify is not found on the server.

Yes, sure, if you want to use curl you need the appropriate harbour and compiler libraries
What C compiler do you use in your development?

Using PATCH did work ! (PUT was not changing data) don't know way, because it should i think

Where do I put the dbf loop to update the data ?
The object http = already created once.

Maybe it is the intension that the loop will fill the cData var and that we patch it only once ?
The cData will become a large file or mem variable then. Do we ever can have memory problems when we do large updates ?

No problem at all.
cData is getting replaced. It is not growing.

Size will be no problem, but cData is in the loop until full processed not ? And then the call to the Function to update by http

API programming... A whole new world is opening ))))

I spend lot's of time creating functions so I could use the import function of the hosting company. With the API I can go direct. Very Nice.
