Our LivePricer tool is used to serve live pricing information into emails/web pages/ads using a dynamically generated image. This tool works from a TC.com search results URL, for which a ‘best’ price is required, along with other parameters such as font, text size and colour.
Once these parameters have been defined, a unique image URL is generated which can be embedded into HTML in the same way any other image would be inserted.
The dynamically generated image will always be up to date at the point of being requested, so for example if an email is opened 2 days after it is sent, the price displayed will still be accurate.
Prices are cached to minimise load. All late availability (within the next 6 weeks) is cached for 2 hours after being first requested, and all other pricing is cached daily. This is in line with TC's general pricing update timings.
