It is possible to use placeholders within your messages, check elements and at other locations. Just type {{ somekey }} and it will be replaced by the value it is representing. Please note that you have to use exactly that format ({, {, space, key, space, }, }). If the replacement value is language-dependent (such as the title of the check recipient), then the check-, user- or account-language is used. If a value is not available, then the placeholder is just removed.
You can use placeholders at these locations:
Besides the standard placeholders above, there are also dynamic placeholders that are based on check elements and account-, user- and check custom values.
