What is an API rate limit and why does it matter to a dealership?
A cap on how many requests a system will accept in a period. It matters because it determines how current your data actually is. A connection described as real time can be limited to a few synchronisations an hour, which is the difference between accurate inventory and a customer arriving for a vehicle that sold yesterday.
Ask for the number, not the adjective
Replace 'real time' with a figure: how many requests, over what period, and what happens when the limit is reached — queued, dropped or failed.
Understand the business consequence
Translate the limit into store terms. If inventory synchronises four times an hour, the exposure is a fifteen-minute window of stale listings and pricing. Decide whether that is acceptable rather than discovering it later.
Check who bears the cost of exceeding it
Some agreements charge for volume above a threshold. Establish the unit, the price and whether a marketing campaign or a large data load can trigger it.
Test at your volume
Limits that are invisible at demo volume become visible at group volume. Ask for a reference operating at your scale.

What is the difference between a DMS and a CRM?
A DMS is normally the operating and financial system of record for deals, accounting, parts and service. A CRM is normally the sales and customer-workflow system for leads, communications, appointments and follow-up. A suite may include both, but the data and workflow boundaries still need to be documented.
Integration verificationHow do you verify a dealership software integration?
Verify both named products and versions, applicable dealerships, data objects, fields, direction, frequency, authentication, provider, fees, monitoring and support ownership. A partner logo or marketplace listing is only a discovery signal.
Write-back definitionWhat does bidirectional integration or write-back mean?
Bidirectional generally means data moves in both directions, while write-back means one system can update another system’s record. Neither phrase is complete until the exact objects, fields, triggers, conflict rules and timing are stated.
Open DMS meaningWhat is an open DMS?
“Open DMS” has no single controlling definition. It may refer to APIs, certified integrations, customer-authorized data access, export capabilities or a commercial marketplace. Dealers should replace the label with specific access and portability requirements.
