How To Fix Invalid Parameter Facebook Ads

If you are utilizing Facebook Ads to promote your company, you may have come across the bothersome issue known as the “Invalid Parameter” error. This error frequently appears when attempting to generate an ad, preventing the process from being completed. However, rest assured that you are not alone, and there are remedies accessible. In this article, we will clarify the potential causes of this problem and offer a detailed tutorial on how to resolve it.

Causes of Invalid Parameter Error

The main reason behind the invalid parameter error in Facebook Ads is often due to discrepancies in the information provided in the ad set or campaign settings. Common causes include:

  • Invalid or unsupported characters in the campaign name
  • Entering an invalid date or time range
  • Setting an incorrect budget
  • Submitting incorrect targeting parameters

Steps to Fix the Invalid Parameter Error

Here’s a step-by-step guide to troubleshoot and fix the invalid parameter error:

Step 1: Check Your Campaign’s Name

Ensure that your campaign name doesn’t include any special characters that Facebook doesn’t support. If it does, change your campaign’s name and remove these characters.

Step 2: Review Your Date and Time Settings

Make sure you’ve correctly entered the date and time settings for your ad campaign. An invalid date range can trigger an invalid parameter error.

Step 3: Check Your Budget

Ensure that the budget you’ve set for your campaign is within Facebook’s accepted range. For instance, if you’ve set a daily budget of less than $1, you might encounter the invalid parameter error. If so, increase your budget.

Step 4: Review Your Targeting Parameters

Finally, review the targeting parameters you’ve set for your campaign. Make certain that all the geographical regions, age ranges, and other parameters you’ve set are valid and supported by Facebook.

When All Else Fails

If you have tried all the above steps and still can’t fix the problem, it might be a glitch on Facebook’s end. In such cases, it’s recommended to contact Facebook’s support team for help.


While the invalid parameter error can be frustrating, it’s usually easy to resolve with a little patience and troubleshooting. By carefully reviewing your campaign settings and ensuring everything is correctly set up, you can get your Facebook Ads back on track and continue promoting your business effectively.
