Common Manus issues affecting integrations
Autonomous security decisions without human review
Manus configures authentication, sets file permissions, and chooses security-sensitive patterns autonomously. These decisions are made without context about your threat model and may be inadequate for your use case.
Unknown packages installed without vulnerability audit
Manus installs dependencies autonomously from web research and may choose packages with known CVEs, low maintenance status, or malicious forks. There is no automatic supply chain security check.
Outdated patterns sourced from web research
Manus browses the web to inform implementation decisions. It can pull code patterns, library versions, and architectural approaches from outdated blog posts or Stack Overflow answers.
SendGrid issues we find in Manus apps
Using deprecated v2 Mail Send API
AI tools generate code using the SendGrid v2 API endpoint and format instead of the current v3 Mail Send API, missing features and facing eventual deprecation.
Sender authentication not configured
Generated code sends from addresses without domain authentication (SPF/DKIM), causing emails to fail or be marked as spam by receiving mail servers.
API key has full access instead of restricted permissions
AI tools create and use API keys with full admin access when only Mail Send permission is needed, creating an unnecessary security risk if the key leaks.

What SendGrid issues does Manus typically create?
Common issues in Manus-generated SendGrid code include: using deprecated v2 mail send api, sender authentication not configured, api key has full access instead of restricted permissions. We fix all of these in our code review.
How much does it cost to fix my SendGrid integration?
Start with our code audit ($19) to get a complete list of SendGrid issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What SendGrid best practices does Manus typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for SendGrid. Our review checks all of these and provides specific fixes.
