Update Product if Product already exist

[JanikHalder]

Hi there,

I want to import products into swell from my PIM on a regular base.
Therefore I want to create products (post request) and if it fails because the PIM-ID (custom field in swell) is not unique, I want to update this product (put request).
Is there a way to do this? Because as the error looks like that:
{
errors: {
sku: { message: 'Already exists', code: 'UNIQUE', fields: [Object] },
slug: { message: 'Already exists', code: 'UNIQUE', fields: [Object] }
}
}
there is no ID returned from the post request, which I can than use to update the product.

I found an easy solution for this problem.

You can check if a product exist by using:

const product = await swell.get('/products', {
where: {
uniqueIdentifier: value,
},
limit: 25,
page: 1,
})

this returns

{
count: numberOfItems,
results: [items],
page: 1,
}

Now you can check if numberOfItems === 0

If it is zero you have to create a new Product,
if it is 1 you get the id of the product by using product.results[0].id and now you can use this id to update the product.

Hope this helps.

Best, Janik

There's another approach also, using the slug field to do a PUT request in a way that works to either create or update the record if it already exists. Here's an example:

await swell.put('/products/{slug}', {
  slug: 'new-or-existing',
  ...
})
