Hello,

Thank you for your answer.
1. Regarding Purchase Event missing some deduplication parameters I don t have an percentaje, just that all my ad Sets are being impacted. I just have this information.

Purchase Event missing some deduplication parameters
You’re sending Purchase events through both your pixel and the Conversions API, but they’re not being deduplicated properly because not enough of these events are receiving an event_id parameter. Event instances sent without an event_id parameter cannot be deduplicated.
This may cause issues with the measurement of your events as well as the attribution and delivery optimisation of any ad campaigns that are optimising for this event.

How to fix the issue
You’ll need to use the solution below to fix the issue.
Once you’ve fixed the issue in your website code, you can mark it as resolved. This will move it to the Previously detected section. If the issue is found again after three days, it will move back to the Active section.
Add an event_id parameter to all Purchase events that you’re sending from both your pixel and the Conversions API. To add an event_id parameter to the events that you’re sending through the Conversions API, you can use the payload helper tool on the Facebook for Developers site to validate that your payload is set up correctly. To add an event_id parameter to the events that you’re sending through your pixel, go into your website’s source code and add an event_id parameter to each of your Purchase event instances.

2. Purchase event missing value parameter
The purchase event sent from your server is missing a value parameter, so it can’t be received or used for ads attribution or optimisation. All purchase events must contain a value parameter and a currency parameter for attribution and optimisation to work.

For this I have 8% Total Purchase events affected .

The most important thing is I need to solfe the problem with deduplication., Because for Now all conversions are counted twice.

What should I do?
