}Check that your response includes the expected fields:
success(boolean)credits_remaining(number)credits_charged(number)searchResults(object)searchResultsCount(number)Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.
Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.
Never expose your API key in client-side code. Use environment variables and secure key management practices.
When scraping multiple ads, consider batching requests to maximize throughput while staying within rate limits.
Use asynchronous processing in C# to handle multiple requests concurrently and improve overall performance.
Analyze Facebook Ad Library ads to understand market trends, competitor analysis, and audience insights.
