Frequently asked questions

Everything you need to know about Zapier.

Still have questions?

Speak with one of our Zapier experts.

How can you integrate Custom API with my other tools?

add_circle_outline

You can integrate Custom API with your tech stack using automation platforms like Zapier, Make.com or n8n. These tools connect Custom API to thousands of applications, automating tasks like data syncing, notifications, document creation, task assignment. Our certified Custom API integration experts design tailored workflows to ensure seamless Custom API integrations with minimum hassle.

We can also develop custom Custom API API integrations.

What Custom API integration services do you offer?

add_circle_outline

We offer Custom API integration/automation consulting, implementation and support (including Custom API integration training). Hop on a free discovery call to discuss your Custom API integration project today: Book a Call.

If you have an Custom API integration issue that needs an urgent fix or need a quick Custom API automation developing, we recommend InstantBuild to help you get it done in the next day or so.

What if Custom API doesn’t have the API functionality or connector for my project?

add_circle_outline

If Custom API lacks the right API endpoint/functionality or iPaaS connector to achieve your needs, we can still usually find a way to automate it. For your Custom API project, the order of preference for automation is: Native Custom API Automation Functions > iPaaS Connector (e.g. Custom API modules in Zapier/Make/n8n) > Custom Custom API API > RPA/Browser Automation (for apps without an API).

If Custom API has the API functionality needed but lacks the right iPaaS connector, we will build your Custom API integration directly with the API.

What if my other apps don’t integrate easily with Custom API?

add_circle_outline

No access to the API, or the API doesn't support a particular data field? No problem. If Custom API's API doesn't support what you need, we can use browser-based automation, called browser bots, to read or write data from the user interface, e.g. log into Custom API like a human would, except done by a robot according to specific automation logic. These browser bot workflows can then be linked into your wider integration solution through webhooks where needed! If you know what you need from your Custom API integration, we'll help you get it - API or no API!

Are Custom API integrations with other tools secure?

add_circle_outline

Yes, generally the technologies used to integrate apps like Custom API are secure! However, the specific security of your Custom API integration will fall to the level of process excellence and experience of whomever is building the integration. When working with flowmondo's experts for your Custom API integration, we follow best practices to secure your systems including: Proper API scope provisioning where possible, credentials encyption, least privilege access logic, Multi Factor Auth by default

How much does it cost and how long does it take to develop an Custom API integration/automation?

add_circle_outline

The cost and timeline to integrate/automate Custom API depends on the complexity of your overall solution. This is influenced by things such as the number of tools besides Custom API to be integrated, data volumes, clarity of the business logic (your way of doing things).

Simple integrations, like a one-way sync of Custom API with a couple of other tools, can usually be set up in a few hours and may cost less. More complex solutions, such as multi-directional data flows in and out of Custom API or advanced solutions requiring custom coding, can take several days and require a higher investment. We prioritise affordability and speed, ensuring you see value quickly. Contact us for a tailored estimation and timeline based on your tech stack and specific Custom API integration needs.

Can I integrate Custom API myself, or do I need an expert?

add_circle_outline

You can likely integrate Custom API yourself using user-friendly tools like Zapier or Make.com, which offer simple triggers and actions for basic automations. However, the complexity often lies in your business logic (rules/processes), even if the concept seems straightforward—such as handling conditional workflows or allocating X task to Z user because of Y relationship. For example, you might need to pull specific data from Custom API that isn’t available in a standard iPaaS (Zapier/Make) connector.

That’s where our certified developers help: we design custom solutions to unlock advanced functionality, saving you time and ensuring error-free, efficient automations while you focus on your business. If you do it yourself - make sure you build in functionality to catch and handle errors and edge-cases that will occur.
