Fixing Marktplaats Pro error 'Value of the field 'cpc' was out of range'

Marktplaats Pro has different minimum CPC values per category. For example, the minimum CPC value for E-readers could be €0.02 and for cars could be €0.04. When the CPC value for an ad is set below the minimum CPC, you will get an error in Channable:

If you click on the error, you will get an overview of the ads for which the CPC value does not reach Marktplaats Pro's minimum CPC value. In this overview you can also see the category ID number, the CPC value that's currently set and the minimum CPC value for products in this category.

To solve these errors follow the steps below.

1

Step 1 — Write down the categories & minimum CPC

From the overview write down the category ID numbers (category column) and the minimum CPC value (error column). For example, the minimum CPC of the screenshots above is €0.03. The snippet "range([3,250])" means the minimum CPC is €0.03 ("range([4,250])" indicates a minimum CPC of €0.04, and so on).

Step 2 — Create a new field for CPC

If you don't have a field in which you can set your CPC values yet, add one.

Add a field called "cpc" or a similar name. This creates an empty field for every product so you can set the CPC value for each Marktplaats Pro ad. If you already have a field for CPC you can use that field in the next steps.

To set the CPC for your products, perform the following actions:

1

Go to Channels -> Marktplaats Pro -> Rules

2

Click "Create new" and choose a name (e.g. "set cpc")

3

Create a rule like the example below, using the category numbers that you have written down.

Step 3 — Add CPC in Build & Run marketplace

Add the CPC field you created (or already had) to the Build step of the marketplace:

• Go to Build > Price Information

• Click the plus and choose the cpc field

Finally, send these changes to Marktplaats Pro:

• Go to Channels -> Marktplaats Pro

• Click "Run now"

The errors should now disappear in the Preview step of your Marktplaats Pro API. If you still see CPC errors, you have probably missed some categories — repeat the steps above for those categories to fix the remaining errors.
