Understanding Propexo vs. PMS Rate Limits
Last updated: March 23, 2026
When working with the Propexo API, it’s important to understand that two types of rate limits may affect your integration:
Propexo’s rate limits, which apply to how often you can call the Propexo API
PMS rate limits, which govern how frequently we can sync data from your connected property management system
While both types of limits can impact performance, they operate independently — and knowing the difference helps you troubleshoot delays, optimize syncs, and avoid unnecessary API calls.
What Are PMS Rate Limits?
Each PMS (e.g. Entrata, Rent Manager) enforces its own set of rate limits. These limits determine how often Propexo can communicate with their APIs on your behalf. PMS rate limits are typically applied:
Per API
Per customer
Per credential set
For example, a PMS might allow:
1,000 requests per minute
5,000 per hour
10,000 per day
And those limits may vary by endpoint or by customer. For instance, fetching new leads might be rate-limited differently than fetching unit data or lease renewals.
How to know missing data is caused by PMS rate limiting?
In Propexo, navigate to the integrations tab.
Then, select your relevant PMS from the list.
On the PMS page, select your integration, then scroll to Sync Results. Here you will be able to see information pertaining to your latest syncs, including rate limited records.
You can also see rate limited records by Vendor endpoint by scrolling to the Integration Vendor Endpoint Usage section.
If you are hitting PMS rate limits, you can adjust your sync concurrency settings.
How Are Propexo’s Limits Different?
Propexo enforces its own rate limits to ensure consistent performance and fairness across customers. These limits apply to calls made to the Propexo API, not to the underlying PMS APIs.
Default limit: 150 requests per minute
Contract-specific limits: Some customers may have higher or lower limits depending on their plan
Rate limit headers: Every Propexo API response includes usage headers (
x-ratelimit-limitandx-ratelimit-remaining) to help you monitor usage in real time
Important: Even if you're well within Propexo’s limits, a sync or write operation may be delayed or limited due to the PMS rate limits in the background. For more information on Propexo rate limits, please refer to this article.
