I need to pass the get api urls for fetch the data from one application to another application. I have temporary solution as the url details in queryParams and use it in another application. Is there any professional way to implement for build url with dynamically?

In my first application i have build the url as below

async buildUrl(applicationId, getUrl) {
        let url = this.filterBaseurl + `datafilter/get-filter-utility?entityId=${applicationId}&connectorName=${this.connectorName}&entityName=${this.entityName}&getUrl=${getUrl}`
        return url
    }

example result of above function is

${baseUrl}/datafilter/get-filter-utility?entityId=12345678&connectorName=greenhouse&entityName=engagement-request&getUrl=jobs

in my another application i have calling the required api url

let queryparams = req.queryParams
let url = ${queryparams.getUrl}/{queryparams.entityId}
let response = await this.restProvider.get(url)

the way i have implement with queryParams is unprofessional, is there any better way to build the api url dynamically. one difficulty is i shouldn't call second application's api endpoint from first application.
