Title: ViewContent Event Missing Deduplication parameter Last modified: July 14, 2021 --- # ViewContent Event Missing Deduplication parameter * Resolved [carnagelp](https://wordpress.org/support/users/carnagelp/) * (@carnagelp) * [4 years, 11 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/) * Please see this screenshot: [https://ibb.co/VDQXYrY](https://ibb.co/VDQXYrY) The pixel is showing this issue and giving the solution to add the event_id using code. As I’m not a coder, I don’t know how to do that. I read the other threads and found out about testing Pixel Helper and it’s all good. Here’s a screenshot for your reference: [https://ibb.co/wdng7KY](https://ibb.co/wdng7KY) * Here’s a Woo-commerce status report which is also not showing any error regarding this problem : [https://pastebin.com/4erGMKE8](https://pastebin.com/4erGMKE8) * I also stumbled upon the following suggested solutions by your team to other members • An unmodified, default WordPress theme such as Twenty Twenty or Storefront active. • No other plugins except for WooCommerce and Facebook for WooCommerce active. * It is not practically possible to apply these solutions as the whole website will collapse and for a non-tech person like me, it will be another hassle to de-activate and reactivate it all again. Also, this solution is being floated around for months now and none of the users in their threads confirmed that it will resolve the above issue so it is a very big risk without any possible benefit. * I’ve also found these active threads on GH: • [https://github.com/woocommerce/facebook-for-woocommerce/issues/2020](https://github.com/woocommerce/facebook-for-woocommerce/issues/2020)• [https://github.com/woocommerce/facebook-for-woocommerce/issues/1722](https://github.com/woocommerce/facebook-for-woocommerce/issues/1722)• [https://github.com/woocommerce/facebook-for-woocommerce/issues/1668](https://github.com/woocommerce/facebook-for-woocommerce/issues/1668) * And it seems like this bug is unresolved. Please let me know if I missed something and there’s any other way to resolve this. * We cannot run ads without the event de-duplication and it’s causing us a loss. Also, Is there any alternative to this plugin/ can we manually add the API using the code given here: [https://developers.facebook.com/docs/marketing-api/conversions-api/payload-helper](https://developers.facebook.com/docs/marketing-api/conversions-api/payload-helper) and remove the plugin? If Yes, then How can we do that? * In summary • Please help me resolve this event with an easier solution than the one above • If this is an unresolved bug, provide a temporary alternative - This topic was modified 4 years, 11 months ago by [carnagelp](https://wordpress.org/support/users/carnagelp/). - This topic was modified 4 years, 11 months ago by [carnagelp](https://wordpress.org/support/users/carnagelp/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fviewcontent-event-missing-deduplication-parameter%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 6 replies - 1 through 6 (of 6 total) * [Summer M.a11n](https://wordpress.org/support/users/shrutiwpcom/) * (@shrutiwpcom) * [4 years, 11 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14661653) * Hi there, * Thank you for the detailed message. We would need to investigate this further to diagnose if this in fact is a bug or not: * 1) Could you please update the Facebook for WooCommerce plugin and see if that helps? [https://github.com/woocommerce/facebook-for-woocommerce/releases](https://github.com/woocommerce/facebook-for-woocommerce/releases) * 2) Do you perhaps have the pixel tracking code added to your site more than once? One thing you can check is your site’s header.php in case the code was added there manually. * 3) You can also check if you have another plugin that may be adding the code. We do understand that placing a site under different conditions while you conflict test may be disruptive. Many people maintain a staging copy of their site for exactly this purpose. That way, testing, and troubleshooting can be done on the staging copy without disrupting the operation of the live site. If your host does not provide an easy way to set up a staging site, you might want to use something like the WP Staging plugin for this purpose: [https://wordpress.org/plugins/wp-staging/](https://wordpress.org/plugins/wp-staging/) * On your staging site, you can try the following conflict test: [https://docs.woocommerce.com/document/woocommerce-self-service-guide/](https://docs.woocommerce.com/document/woocommerce-self-service-guide/) * Please let us know how this goes! * Thread Starter [carnagelp](https://wordpress.org/support/users/carnagelp/) * (@carnagelp) * [4 years, 11 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14665760) * I tried what you mentioned and now that error doesn’t seem to be there anymore. However, I now get this error: [https://ibb.co/rvy3Pyv](https://ibb.co/rvy3Pyv) * [mouli a11n](https://wordpress.org/support/users/mouli/) * (@mouli) * [4 years, 11 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14670425) * [@carnagelp](https://wordpress.org/support/users/carnagelp/) Please can you confirm that you have tested this on a staging site and done a full conflict test as suggested by [@shrutiwpcom](https://wordpress.org/support/users/shrutiwpcom/)? It looks like Facebook is getting duplicate data from the Facebook plugins API and the pixel which it then cannot `deduplicate`. I concur that the first thing to check here would be for a conflict between your plugins and/or theme. * [nilewm](https://wordpress.org/support/users/nilewm/) * (@nilewm) * [4 years, 10 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14677650) * I am also having a deduplication problem.. * I’ve deactivated/reactivated the plugin and confirmed that the pixel was taken off my website (using the pixel helper) before reactivating. * I also reimplemented the Facebook API integration and confirmed with my Facebook ads manager that the API is firing correctly. However, I’m still getting deduplication errors. * I’m thinking this is a plugin issue because I am receiving multiple “browser” events from the ‘partner integration’ being the facebook for woocommerce plugin. * The facebook pixel code is only on my website via the plugin as I’ve verified by turning the plugin off and checking the pixel helper as mentioned previously. * Any help with this would be greatly appreciated as I need accurate metrics to make informed decisions for my business! * [Summer M.a11n](https://wordpress.org/support/users/shrutiwpcom/) * (@shrutiwpcom) * [4 years, 10 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14686542) * Hi [@nilewm](https://wordpress.org/support/users/nilewm/) , * 1) Could you share the exact error messages that you see? Please share screenshots if possible. I recommend [https://snipboard.io](https://snipboard.io) for sharing screenshots – please follow the instructions on the page, then paste the URL in this message. * 2) Another thing you can look at is if you have a caching plugin. You can try disabling that and seeing if it will help. * 3) Lastly could you also confirm if you have already conflict tested on your site? I recommend creating a staging site and following this guide: [https://docs.woocommerce.com/document/woocommerce-self-service-guide/#section-4](https://docs.woocommerce.com/document/woocommerce-self-service-guide/#section-4) * Thanks! * [Augustus – a11n](https://wordpress.org/support/users/augustuswp/) * (@augustuswp) * [4 years, 10 months ago](https://wordpress.org/support/topic/viewcontent-event-missing-deduplication-parameter/#post-14721727) * We haven’t heard back from you in a while, so I’m going to mark this as resolved– we’ll be here if and/or when you are ready to continue.
